In what other way can acceleration occur besides there being a change in velocity?

What is the difference between average velocity and instantaneous velocity?

An airplane’s engines stall out while in flight then, after a few minutes, they start up again and the plane continues on its way. What must be true of this situation in order for you to be able to use Kinematic equations, even if you were given measurements in time, displacement, and/or velocities?

THIS IS A CALCULATION PROBLEM:

An object on a number line moved from x = 13.0 cm to x = 125 cm and then moved back to x = 25.0 cm, all in a time of 100. seconds. What was the average velocity of the object?

THIS IS A CALCULATION PROBLEM:
