What is a contact, non-contact and normal contact force?

Contact forces are when two objects are physically touching. E.g. air resistance when air particles collide with a parachute, and friction that happens when an aeroplane lands on the sea, which cause it to slow down. Non-contact forces are when two objects are physically separated, e.g. the electrostatic force, which is the force between two charged objects. While a normal contact force is when two objects are in direct contact and both forces exert a force upon one another, e.g. an aeroplane flying through the air or a book on a table.
