Question

Define average velocity and instantaneous velocity. When are they same?​

Answer 1

Answer:

Instantaneous is the velocity of an object in motion at specific point in time. This is determined to simple average velocity but we narrow the period of time it approaches zero

Answer 2

Velocity is the change in position divided by the change in time, and the instantaneous velocity is the limit of velocity as the change in time approaches zero. This is equivalent to the derivative of position with respect to time. Instantaneous velocity is a vector, and so it has a magnitude (a value) and a direction.

Average velocity is equal to the instantaneous velocity when acceleration is zero. In order for acceleration of an object to equal zero, there can be no change in speed or direction. For example, when a car is traveling down a straight road on flat land using cruise control.
