Otherwise, newton's first law of motion says that an object will continue to stay at rest or at a until a force is applied to it.

The Newton’s law of motion in first law states that an object will continue to stay at rest or in a motion until unless an external imbalance force is applied to the body.

Explanation:

The inertia of rest and motion is continued in the body until an external imbalance force is experienced over the body. The body continues to stay in rest if it is in rest or stays in motion if in motion. The velocity is constant when the object is at rest.
