Force It Really Moves

Force: That which causes a free body to undergo acceleration.

There are 4 fundamental  forces in Nature.
Gravity: The mutual attraction of all matter in the universe.
Electromagnetism: The mutual attraction and repulsion of charged partials.
Weak nuclear force: Regulates some types of nuclear decay including Bata decay.
Strong nuclear force: The Binding force of the atomic nucleus.

Forces cause the acceleration of mater which isby definition the main function of force . It can overcome other forces such as friction gravity abd the Strong nuclear force overcomes the mutual electromagnetic repulsion of protons that would blow every atomic nucleus apart. Force also holds things together. The electromagnetic force holds an object together including your body and the strong nuclear force holds atomic nuclei together. It can break things apart such as bombs or the force resulting from ramming two things together which can cause them to shatter and the peaces to fly apart.

Regardless of its source force causes acceleration. Force can also stop acceleration by resisting another force. Force holes thing together so force does indeed bind us together so it looks like Ben Kenobi got it partly right. Force makes our existence possible.
