If the net force acting on an object is zero, the motion of the object does not change
Newtons first law of motion
If the net force acting on an object is zero, the motion of the object does not change. Newton's First Law of Motion. In simple terms, it means that an object will keep doing what it's doingstaying still or movingunless a force makes it change.

The acceleration of an object is the net force exerted on it divided by its mass
Newtons second law of motion
The acceleration of an object is the net force exerted on it divided by its mass. Newton's second law of motion. In simple terms, this means that the harder you push or pull something, the more it speeds up, depending on how heavy it is.
