Changes in Force & Motion Review

What is net force?

• A system that uses coordinates or background objects to establish position or measure movement of a point in space.

• The sum of all the forces acting on an object.

• A straight path an object can move along.

• Separate forces on an object that, combined, do not change the movement of the object.
