Which has zero acceleration? An object
A)at rest.
B)moving at constant velocity.
C)in mechanical equilibrium.
D)all of the above
E)none of the above

Question

Quizplus · Accepted Answer

An object with zero acceleration means that its velocity is not changing. This occurs in the following situations:
A) An object at rest has zero velocity and thus zero acceleration.
B) An object moving at constant velocity has a non-zero velocity, but its velocity is not changing, so it has zero acceleration.
C) An object in mechanical equilibrium is balanced such that the total forces acting on it are zero, and thus it has no acceleration.

Therefore, all of the above choices have zero acceleration.
