Learn what the kinematic equations are and how you can use them to analyze scenarios involving constant acceleration.

You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time, such as miles per hour or kilometers per hour.

Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) …

Learn how to find an object’s instantaneous speed or velocity in three ways - by using calculus, by looking at the slope of a given point on a graph of an object’s rate vs. time, or by using kinematic …

Worked example of calculating displacement from time and velocity. Learn how velocity, time, and direction factor into calculating displacement. Understand the importance of unit conversion in these …

Let's work through another few scenarios involving displacement, velocity, and time, or distance, rate, and time. So over here we have, Ben is running at a constant velocity of three 3 meters per second …

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your …

Displacement in physics is a vector quantity that measures the change in position of an object over a given time period. Learn how to calculate an object’s displacement as a function of time, constant …

Review the key concepts, equations, and skills for uniform circular motion, including centripetal acceleration and the difference between linear and angular velocity.

Let's learn what average speed & velocity are using some examples. Created by Mahesh Shenoy.
