which describes a positive or negative net force acting on an object? check all that apply.\nit can cause an…

Brief Explanations:

According to Newton's second - law of motion ($F = ma$), a non - zero net force (positive or negative) causes a change in an object's motion. Acceleration is a change in velocity (which can be a change in speed or direction). An object at rest will start moving if a net force acts on it, an object in motion can stop moving or change directions due to a net force. An object at rest remains at rest only when the net force is zero.

Answer:

It can cause an object to accelerate. It can cause an object to stop moving. It can cause an object to start moving. It can cause an object to change directions.
