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.
There is two types of forces they are contact forces and non-contact forces. Contact forces are forces that are applied when physically touching. Non-contact forces are forces that don’t physically touch when applied. Some examples for contact forces are a person throwing a ball or writing on paper. The contact forces are push, pull and friction. Some examples for noncontact forces are a magnet and a paperclip and the moon’s gravity and the earth’s tides. The two noncontact forces are magnetism and gravity.
