Question

question 19 (1 point)
when is the average velocity of an object equal to the instantaneous velocity?
always
never
only when the velocity is constant
only when the velocity is increasing at a constant rate

Explanation:

Average velocity is total displacement over total time. Instantaneous velocity is velocity at a specific moment. When velocity is constant, every moment's velocity (instantaneous) is same as average over any time - interval. For non - constant (changing) velocities (either increasing non - constantly or at a constant rate), average and instantaneous velocities differ.

Answer:

only when the velocity is constant
