Acceleration-1

The video tutorial explains acceleration as the rate of change in an object's velocity, which can be an increase or decrease in speed or a change in direction. Acceleration is a vector quantity, meaning it has both magnitude and direction. The video provides examples, such as a baseball starting or stopping, to illustrate how acceleration works. It also discusses how acceleration can affect an object's velocity depending on the direction of the acceleration relative to the velocity. Finally, the video summarizes the three ways acceleration can change velocity: by altering speed, direction, or both.

What happens to the velocity of an object if the direction of acceleration is opposite to the direction of velocity?

In what ways can acceleration change an object's velocity?
