Forces give an object the energy to move, stop or change its direction.
Types of forces:
  1. Contact forces: There's a contact between two objects, two people or a person and an object.
  • To push: to move an object forwards.
  • To pull: to move an object backwards.
      2. Non-contact force: no contact takes place.
  •  Gravitya force that attracts an object to another.
         It is the force that pulls everything towards the Earth's surface.

  • Magnetism: It is the force the magnets produce.
