What is an object doing at the moment its instantaneous acceleration is zero?

A. Resting

B. Changing Direction

C. Traveling Downward

D. Accelerating

Answer: Option A

Explanation:

Acceleration is defined as the rate of change of the vellocity.

Then, if the acceleration is equal zero, the object has a constant velocity or a velocity equal to zero (also constant, of course)

Then, te correct option would be option A; resting, because an object resting has instantaneuos acceleration of zero.
