Forces make objects move.

 

Some forces need a contact between two objects, like your bike wheel on the ground as you cycle, or your hand on a spoon as you stir a saucepan of food.

 

Others work without any direct contact with the object they act on, like magnetism and gravity: they can exert a force over a distance without touching anything.

 

Pushing and pulling are examples of contact forces.

Magnetism and gravity are examples of non-contact forces.
