When the velocity of an object does not change, what happens to its acceleration?
Ratling [72]

Answer:

Acceleration is the rate of change of velocity.

When the velocity of an object does not change, i.e., when the velocity is constant, the acceleration is <em>zero</em>.

Mathematically (differential form),

Velocity = k, \: where \: k \: is \: a \: constant \\  \frac{d(Velocity)}{dt}  = 0 \\\boxed{ Acceleration = 0}✓
