A force is a push or a pull exerted on an object. They are of two types:

Contact force: A force in which there is actual contact between the agent and the object. Example: muscular force, frictional force, normal force of reaction

Non contact force: A force in which there is no actual contact between the agent and the object. Example: gravitational force, magnetic force, electrostatic force.

I hope I helped :)
