Question

Which of the following statements shows an object with zero acceleration?

a. The object's acceleration is not constant.
b. The object's acceleration is constant.
c. The object's velocity does not change.
d. The object's velocity changes.

Answer 1

Answer:

C

Explanation:

if velocity doesn't change,acceleration is zero.

Answer 2

Answer:

c. The object's velocity does not change.

Explanation:

The object's velocity does not change means the velocity is constant. Since, acceleration is the rate of change of velocity ! We need a change in velocity to calculate acceleration . Since it is constant , no change in velocity , no acceleration . Therefore acceleration is said to be zero .
