Measuring Units and Significant Figures

Ever wondered why your calculator shows way more decimal places than you should actually write down? That's where significant figures come to save you from looking like you measured something with impossible precision.

Significant figures tell us how precise our measurements really are. They include all the digits we're sure about, plus one estimated digit. Think of it this way - if your ruler only shows millimeters, you can't claim to know something down to the micrometer!

Here are the key rules you need to memorize All non-zero digits always count (274 has 3 sig figs). Zeros between other digits count too (1,008 has 4 sig figs). But leading zeros before the first non-zero digit? They don't count at all (0.0025 only has 2 sig figs).

Quick Tip When doing calculations, addition/subtraction follows decimal places, while multiplication/division follows the number with the least significant figures.

Scientific Notation and Physical Quantities

Nobody wants to write out 602,000,000,000,000,000,000,000 every time they talk about atoms! Scientific notation saves your hand from cramping by expressing huge or tiny numbers as powers of 10.

The trick is moving that decimal point until you have just one digit to the left of it. Move left for big numbers (positive exponent), move right for tiny numbers (negative exponent). So 65,000 becomes 6.5 ร— 10โด, and 0.009807 becomes 9.807 ร— 10โปยณ.

Physics deals with two types of quantities fundamental and derived. Fundamental quantities like length (meters), mass (kilograms), and time (seconds) are the building blocks. Derived quantities like speed m/sm/s are combinations of the fundamentals.

Real Talk Scientific notation isn't just for show - it's essential for keeping track of significant figures in massive or microscopic measurements.

Measurement Systems Metric vs English

The metric system is basically physics on easy mode. Everything works in factors of 10, so converting is just about moving decimal points. Remember "King Henry Doesn't Usually Drink Chocolate Milk" for kilo-hecto-deca-UNIT-deci-centi-milli.

Converting 2.5 kilometers to meters? Count three places right from kilo to the base unit, so move that decimal three places 2,500 meters. Converting 15 centigrams to decagrams? Count three places left from centi to deca, so you get 0.015 decagrams.

The English system is where things get messy. You need conversion ratios instead of simple decimal moves. Remember that 1 foot = 12 inches, 1 mile = 5,280 feet, and 1 ton = 2,000 pounds. These ratios always equal 1, which is why the math works.

Study Hack Master the metric prefixes first - they'll save you tons of time on calculations and reduce silly mistakes.

Unit Conversions and Vector Introduction

Converting between systems gets tricky but follows a pattern. Always set up your conversion ratios so unwanted units cancel out. Converting 25 m/s to inches per minute? Chain your conversions meters to centimeters to inches, and seconds to minutes.

Now let's talk vectors - these are quantities that need both magnitude and direction to make sense. Scalar quantities like speed, distance, and temperature only need a number. But vector quantities like velocity, displacement, and force need direction too.

Think about it "I'm going 60 kph" (scalar speed) versus "I'm going 60 kph north" (vector velocity). The direction completely changes what's happening! Same with saying "I moved 5 meters" (scalar distance) versus "I moved 5 meters southeast" (vector displacement).

Memory Trick If you can add "in what direction?" to a quantity and it makes sense, it's probably a vector.

Representing and Adding Vectors

Drawing vectors is like creating a map - the arrow's length shows magnitude, and where it points shows direction. Always use compass directions (north, south, east, west) instead of relative terms like "up" or "left" because those change depending on your perspective.

When measuring angles, start from east or west and go toward north or south. So "45ยฐ south of east" means you start pointing east, then rotate 45ยฐ toward south. This keeps all angles between 0ยฐ and 90ยฐ, making calculations cleaner.

Vector addition using the polygon method connects vectors head-to-tail, like following a treasure map. Draw the first vector from the origin, then start the second vector from where the first one ends. The resultant vector connects the starting point to the final endpoint.

Pro Tip The polygon method gives you a visual understanding of what's really happening when forces or motions combine.

Analytical Vector Methods

The component method uses trigonometry to break vectors into x and y parts. For any vector, the x-component equals magnitude ร— cos(ฮธ), and the y-component equals magnitude ร— sin(ฮธ). Think of it as finding the shadow the vector casts on each axis.

Pay attention to signs! Vectors pointing east or north give positive components, while vectors pointing west or south give negative components. This is crucial for getting the right direction in your final answer.

To find the resultant, add all x-components together and all y-components together. Then use the Pythagorean theorem R = โˆš(ฮฃx)2+(ฮฃy)2(ฮฃx)ยฒ + (ฮฃy)ยฒ. The angle comes from tanโปยนฮฃy/ฮฃxฮฃy/ฮฃx.

Key Insight The analytical method gives exact answers, while the graphical method helps you visualize what's happening - use both for complete understanding!

Vector Calculations and Problem Solving

When solving vector problems analytically, organize everything in a table with columns for magnitude, angle, x-component, and y-component. This prevents mistakes and makes checking your work easier.

Remember the quadrant rules for determining direction positive x and y means "north of east," positive x and negative y means "south of east," and so on. The signs of your final components tell you which quadrant your resultant vector points toward.

Vector subtraction just means adding the negative of a vector. To get the negative, flip the direction 180ยฐ. So if vector A points "30ยฐ north of east," then -A points "30ยฐ south of west."

Test Strategy Always double-check your angle calculations - wrong signs on components are the most common mistake in vector problems.

Advanced Vector Operations

For complex vector problems, break everything down step by step. When you see something like D = A - B - C, rewrite it as D = A + โˆ’B-B + โˆ’C-C. Then find the components of -B and -C by flipping their directions.

The component method works the same way regardless of how many vectors you're combining. Just make sure to get the signs right for each component based on the vector's actual direction after considering any negative signs.

Both graphical and analytical methods should give you similar answers. Small differences come from measurement errors or rounding, but if your answers are way off, check for sign errors or calculation mistakes.

Reality Check Vector problems model real situations like forces on bridges or airplane navigation - getting the direction wrong could be catastrophic!

Introduction to Motion Distance vs Displacement

Kinematics studies how things move without worrying about what causes the motion. It's like being a motion detective - you observe and measure, but don't ask "why" yet.

Distance is the total path traveled (scalar), while displacement is the straight-line distance from start to finish (vector). Think of distance as your car's odometer reading, and displacement as "how far you are from home as the crow flies."

If you walk 15 miles east then 5 miles west, your total distance is 20 miles, but your displacement is only 10 miles east. Distance can never be negative and never decreases, but displacement can be positive, negative, or zero.

Real Example GPS navigation shows you the shortest route (displacement thinking) but also tracks total miles driven (distance thinking) - both matter for different reasons!

Speed, Velocity, and Motion Analysis

Speed tells you how fast you're moving (scalar), while velocity tells you how fast AND in what direction (vector). Average speed = total distance รท time, while average velocity = displacement รท time.

Here's the key difference if you drive around the block and end up back home, your average velocity for the trip is zero (no displacement), but your average speed definitely wasn't zero (you covered distance).

For problems involving right triangles, use the Pythagorean theorem to find displacement. If Mary walks 30m west then 100m south, her displacement is โˆš(30ยฒ + 100ยฒ) = 104.30m at an angle you can find using trigonometry.

Connect the Dots These motion concepts build toward understanding acceleration and forces - master distance/displacement and speed/velocity now to make future topics easier.

Speed, Velocity, and Motion Analysis

Speed tells you how fast you're moving (scalar), while velocity tells you how fast AND in what direction (vector). Average speed = total distance รท time, while average velocity = displacement รท time.

Here's the key difference: if you drive around the block and end up back home, your average velocity for the trip is zero (no displacement), but your average speed definitely wasn't zero (you covered distance).

For problems involving right triangles, use the Pythagorean theorem to find displacement. If Mary walks 30m west then 100m south, her displacement is โˆš(30ยฒ + 100ยฒ) = 104.30m at an angle you can find using trigonometry.

Connect the Dots: These motion concepts build toward understanding acceleration and forces - master distance/displacement and speed/velocity now to make future topics easier.

Napakadaling gamitin at maganda ang disenyo ng app. Nahanap ko lahat ng hinahanap ko hanggang ngayon at natuto ako ng marami mula sa mga presentasyon! Tiyak na gagamitin ko ang app para sa isang takdang-aralin sa klase! At siyempre, nakakatulong din ito bilang inspirasyon.

Sobrang ganda talaga ng app na ito. Maraming mga study notes at tulong [...]. Ang problemang subject ko ay Pranses, halimbawa, at ang app ay may maraming options para tumulong. Salamat sa app na ito, bumuti ang Pranses ko. Irerekumenda ko ito sa lahat.

Samantha Klich

Wow, talagang namangha ako. Sinubukan ko lang ang app dahil nakita ko itong ina-advertise nang maraming beses at sobrang nagulat ako. Ang app na ito ang TULONG na gusto mo para sa paaralan at higit sa lahat, nag-aalok ito ng maraming bagay, tulad ng workouts at fact sheets, na SOBRANG nakatulong sa akin.

Thomas R

Napakaganda talaga. Nakakapag-review ako ng 10x mas mabuti, itong app ay mabilis na 10/10. Lubos kong inirerekomenda ito sa lahat. Pwede akong manood at maghanap ng notes. Pwede kong i-save ang mga ito sa subject folder. Pwede kong i-review anumang oras kapag bumalik ako. Kung hindi mo pa nasubukan ang app na ito, marami kang nawawala.

Ang app na ito ay nagpapalakas ng loob ko sa paghahanda sa exams, hindi lang dahil sa pagpapataas ng aking kumpiyansa sa sarili sa pamamagitan ng mga feature na nagpapahintulot sa iyo na makipag-connect sa iba at mabawasan ang pakiramdam na nag-iisa, kundi pati na rin sa paraan na nakatuon ang app sa pagpapagaan ng iyong pakiramdam. Madali itong i-navigate, masaya gamitin, at nakakatulong sa sinumang nahihirapan sa kahit anong paraan.

David K

iOS user

Sobrang galing ng app! Ilalagay ko lang ang paksa sa search bar at makakakuha na ako ng sagot kaagad. Hindi ko kailangang manood ng 10 YouTube videos para maintindihan ang isang bagay, kaya nakakatipid ako ng oras. Lubos na inirerekomenda!

Sa paaralan, napakahina ko sa math pero salamat sa app, mas mahusay na ako ngayon. Lubos akong nagpapasalamat na ginawa niyo ang app na ito.

napakareliable na app para tumulong at palawakin ang iyong mga ideya sa Math, English at iba pang mga related na paksa sa iyong mga gawain. gamitin mo ang app na ito kung nahihirapan ka sa mga area, susi ito para diyan. sana nag-review na ako dati. at libre rin ito kaya huwag mag-alala tungkol diyan.

Alam kong maraming apps gumagamit ng fake accounts para mapataas ang kanilang reviews pero ang app na ito ay deserve lahat ng papuri. Dati nakakakuha ako ng 4 sa aking English exams at ngayon nakakuha ako ng grade 7. Hindi ko pa alam ang app na ito tatlong araw bago ang exam at nakatulong ito ng SOBRA. Pakisuyong maniwala sa akin at gamitin ito dahil sigurado akong makikita mo rin ang mga pagbabago.

Grabe talaga ang app na to. Sobrang nakakaboring sakin ang pagreview pero ginagawa ng app na to na sobrang dali mag-organize ng lahat at pwede mong tanungin ang libreng ai para subukin ang sarili mo kaya sobrang buti at madali mong ma-upload ang sarili mong mga bagay. highly recommend bilang isang taong nagte-take ng mocks ngayon
