That which causes a free body to undergo acceleration is called foece.
There are four fundamental forces in Nature. They are gravity which is the mutual attraction of all matter in the universe it is what holds you to the Earth, electromagnetism which is the mutual attraction and repulsion of charged partials, the weak nuclear force is that which regulates types of nuclear decay such as Bata decay by overcoming the strong nuclear force and the strong nuclear force is the binding force that holds the atomic nucleus together against the tendency of positively charged protons.
Force causes mater to accelerate which is the main function of force by definition. It can be used to overcome other forces such as friction gravity. Force also holds things together since 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
