Answer:

A push or a pull

Explanation:

The only way an object accelerates is if there is a net force acting on it.

When something is at constant velocity(no acceleration), then there is no net force on the object.

No Net force means when you draw a diagram of all the forces on an object, the magnitude of the forces has to cancel out.

Having Net force means when you draw a diagram of all the forces on an object, one of the forces outweigh the other creating a acceleration.
