The physics of motion explores key concepts like distance, displacement,... Show more
This page delves deeper into the representation and addition of vectors, as well as introducing distance-time graphs.
Vectors are visually represented as arrows:
Highlight: The length of the arrow represents the magnitude of a quantity, while the direction of the arrow represents the direction of the vector quantity.
The page explains vector addition with a simple diagram and formula: R = A + B.
An interesting comparison is made between speed and velocity:
Example: If two people stand back-to-back and walk away from each other at the same speed but in opposite directions, their speeds are the same, but one will have positive velocity and the other will have negative velocity.
The page then transitions to discussing distance-time graphs:
Highlight: An object's speed is shown by the gradient of the distance-time graph.
The page concludes by explaining how changes in speed are reflected in distance-time graphs:
This page focuses on speed-time graphs and velocity-time graphs, essential tools for analyzing motion in physics.
Speed-time graphs have the following characteristics:
Highlight: If an object's speed is constant, then the speed-time graph will be horizontal. If the object is not moving , the graph will run along the x-axis because that is where y=0.
The page explains that acceleration determines the change in speed:
An important concept introduced is the area under a velocity-time graph:
Definition: The area under a velocity-time graph is equal to the distance travelled by an object.
To calculate this area, the graph can be broken down into smaller shapes:
The page concludes by mentioning average speed:
Definition: The average speed is the total distance travelled divided by the total time taken.
It's noted that speed can be measured using light gates in experimental setups.
This page focuses on practical methods for measuring speed and acceleration, particularly using light gates in experiments.
Light gates are used to measure speed:
Example: A trolley with a card attached is rolled down a ramp. The light gate records how long it takes for the card to pass through, allowing for speed calculation.
The equation for speed using light gate measurements is introduced:
Vocabulary: v = l / t, where v is speed, l is the length of the card, and t is the time taken to pass through the gate.
The page then presents the general equation for average speed:
Definition: Average Speed = Total Distance / Total Time
An example problem is given:
Example: Usain Bolt broke a world record when he ran 100m in 9.58 seconds. His average speed was calculated as 100 / 9.58 = 10.4 m/s.
The concept of uniform acceleration is introduced, along with several equations:
Where:
Highlight: These equations relate velocity, distance, acceleration, and time for uniformly accelerated motion.
This page presents a problem involving uniform acceleration:
Example: A ball rolling down a hill accelerates uniformly from rest to a velocity of 5 m/s in 10 seconds.
The problem likely continues on the next page, demonstrating how to apply the equations of motion to solve real-world physics questions.
This example illustrates the practical application of the concepts and equations introduced in the previous pages, reinforcing the importance of understanding uniform acceleration in physics.
This page introduces the fundamental concepts of scalar and vector quantities in physics, with a focus on distance and displacement.
Distance is defined as a scalar quantity that measures how far an object moves. It only has magnitude and no direction. In contrast, displacement is a vector quantity that describes both the magnitude and direction of an object's change in position.
Definition: A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction.
The page also touches on the difference between speed and velocity:
Highlight: Velocity describes an object's direction as well as its speed, making it a vector quantity. Speed, on the other hand, is a scalar quantity.
Examples of vector quantities include acceleration, force, velocity, and displacement. Scalar quantities include distance and speed.
Example: If an object moves in a straight line from a starting point to a finishing point, the displacement is a vector quantity representing this change in position.
The page concludes by emphasizing that scalar quantities only have magnitude, while vector quantities have both magnitude and direction.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀
