Goal #2 – Motion and Forces
... If the net force on the object is zero, then all the forces are balanced, and the object will not change its motion. (3rd Law) When one object exerts a force on another object, the second object exerts an equal but opposite force on the first object. (Action-reaction) As an object falls freely, if w ...
