Question

what happens to an object in equilibrium? it remains at rest. its velocity changes. its velocity remains constant. it accelerates.

Explanation:

An object in equilibrium has zero net - force acting on it. According to Newton's first law, when the net - force on an object is zero, its velocity remains constant. This includes the case where the object is at rest (velocity = 0, which is a constant value), but also includes cases where the object is moving with a non - zero constant velocity. A change in velocity or acceleration implies a non - zero net force.

Answer:

It's velocity remains constant.
