A force is a push or a pull. Some forces only work when objects touch. These are contact forces. Kicking, throwing, squeezing and friction are contact forces.
Other forces can act from a distance, without touching. These are non-contact forces.
Gravity pulls everything towards the Earth. Magnetism lets magnets attract (pull) or repel (push) other magnets and attract things made of iron or steel. Static electricity happens when some objects are rubbed together: a rubbed balloon can attract your hair or bits of paper.
Non-contact forces usually get weaker as objects move further apart.
