Forces give an object the energy to move, stop or change its direction.
Types of forces:
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.
Gravity: a force that attracts an object to another.
It is the force that pulls everything towards the Earth's surface.
