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

Question

Quizplus · Accepted Answer

All of these scenarios describe situations where the acceleration is zero: an object in mechanical equilibrium has no net forces acting on it and thus no acceleration; an object at rest is not accelerating because its velocity is not changing; and an object moving at constant velocity is not accelerating because its speed and direction remain constant.
