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 includes both magnitude and direction. Let's learn more about acceleration in this video.

Explore the physics of an Airbus A380 take-off with Khan Academy. Learn how to calculate the time it takes for the aircraft to reach takeoff velocity using principles of acceleration and velocity. This practical example brings the concepts of speed, time, and acceleration to life.
