Forces can be balanced or unbalanced. Balanced forces occur when two equal forces acting on an object in opposite directions cancel each other out, resulting in no net force and no acceleration. Unbalanced forces occur when the forces are not equal, resulting in a net force that causes the object to accelerate in the direction of the larger force. Inertia is an object's resistance to changes in its motion. Objects with greater mass have greater inertia and are harder to accelerate or change the motion of than objects with less mass.
the relation between force and motion id described in Newtons three laws of motion. These laws are very simple statements and enable us to describe the future (or past) motion of body if we know the forces acting on it.
Newton's First Law of Motion: I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This we recognize as essentially Galileo's concept of inertia, and this is often termed simply the "Law of Inertia".

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.

18. Inertia & Mass If you had a tennis racket and I threw a tennis ball at you, what would happen? If you had a tennis racket and I threw a bowling ball at you, what would happen? Why could you change the motion of the tennis ball but not the motion of the bowling ball?
