Learn the kinematic formulas for calculating displacement, velocity, and acceleration in one-dimensional motion.
Acceleration - Khan Academy
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it …
Total final velocity for projectile - Khan Academy
Well, our change in velocity is our final vertical velocity minus our initial vertical velocity. And we know what our initial vertical velocity is, we solved for it. Our initial vertical velocity, we figured out, was 29.54 meters per second.
Calculating relative velocity (video) | Khan Academy
How do we calculate the velocity of one object as seen by another object? In this video, we will intuitively figure out how to calculate relative velocities with some examples. We'll then write down the general expression for calculating relative velocity.
Average speed & velocity (with examples) - Khan Academy
Let's learn what average speed & velocity are using some examples. Created by Mahesh Shenoy.
Impact velocity from given height - Khan Academy
So what we're going to do is given an h, and given that their initial velocity is 0 and that our acceleration is negative 9.8 meters per squared, we want to figure out what our final velocity is going to be right before we hit the ground.

Learn about the concept of power in physics, including how to calculate average and instantaneous power.
Position, velocity, and speed (video) | Khan Academy
The rate that an object's position changes is called velocity. Average velocity is calculated as change in position divided by change in time. Position and velocity are vector quantities.
