A comprehensive guide to equations of motion in kinematicsand projectile motion, covering fundamental concepts of motion, acceleration,... Show more
This page expands on kinematics equations, introducing the third equation of motion and providing practical examples of their application in real-world scenarios.
Definition The third equation of motion relates final velocity to initial velocity, acceleration, and displacement without requiring time.
Example A detailed problem solving example shows a car accelerating from 20ms⁻¹ to 30ms⁻¹ with acceleration of 0.5ms⁻², calculating the distance traveled.
Highlight The UVATS system (Initial velocity, Final velocity, Acceleration, Time, Displacement) is essential for solving kinematics problems - you need three quantities to find the other two.
This page introduces the concept of projectile motion and the effects of gravity on falling objects.
Definition A projectile is an object moving through air under the influence of gravity alone, experiencing constant acceleration of 9.8ms⁻² downward.
Highlight Horizontal motion maintains constant velocity while vertical motion experiences constant acceleration due to gravity.
Vocabulary
This page focuses on the analysis of objects thrown vertically upward and their motion characteristics.
Example A ball thrown upward at 25ms⁻¹ demonstrates the principles of deceleration during ascent and acceleration during descent.
Highlight In vertical projectile motion, acceleration is always negative , affecting both upward and downward motion.
This page examines the characteristics and calculations involved in horizontal projectile motion.
Definition Horizontal projectile motion combines constant horizontal velocity with vertical acceleration due to gravity.
Highlight The actual velocity at any point can be determined using vector addition of horizontal and vertical components.
This page explores projectile motion when objects are launched at angles to the horizontal.
Definition Angled projectile motion combines both horizontal and vertical components, creating a curved path.
Vocabulary
This page concludes with practical applications of projectile motion and force components.
Example A projectile fired at 45° with initial vertical velocity component of 30ms⁻¹ demonstrates maximum height calculation.
Highlight Vector components can be calculated using trigonometric relationships
This page examines vector resolution and force components in projectile motion.
Example A projectile fired at 45° with initial vertical velocity of 30ms⁻¹ demonstrates maximum height calculations.
Definition Vector components are the horizontal and vertical parts of a vector quantity.
Vocabulary Component resolution involves breaking down vectors into horizontal (Vcosθ) and vertical (Vsinθ) components.
This page presents various types of motion graphs and their interpretation.
Definition Motion graphs show relationships between displacement, velocity, acceleration, and time.
Highlight Different types of motion produce characteristic graph shapes that can be analyzed to understand motion behavior.
Vocabulary Graph interpretation requires understanding of positive and negative directions in both horizontal and vertical motion.
This page introduces fundamental concepts in kinematics and presents the first two equations of motion. The content focuses on understanding acceleration, velocity, and displacement calculations.
Definition Deceleration is defined as negative acceleration, occurring when an object's velocity decreases over time.
Highlight The first equation of motion is crucial for calculating final velocity when initial velocity, acceleration, and time are known.
Example A car starting from rest accelerates at 8ms⁻² for 4 seconds, reaching a final velocity of 32ms⁻¹.

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
