The force which acts on an object without coming physically in contact with it is called non contact force. Learn about its types i.e. Gravitational Force, Magnetic Force & Electrostatic Force.
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
