Forces

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.

 

•  Gravity:  a 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.
