A force is a push or a pull on an object. The unit in which we measure force is a newton (N). It is named after Sir Isaac Newton, an English physicist and mathematician. Sir Isaac Newton is recognised as one of the most influential scientists of all times. The unit of force is named after him in recognition of his work in mechanics and his three laws of motion. In this lesson we take a look at what forces are and the different types of forces that exist.

Gravitational force
Gravitational force causes things to fall down towards the Earth and prevents us from falling off the planet is the gravitational force. Gravitational forces exist between any two objects with mass and they are forces of attraction (pull). In this lesson we take a closer look at gravitational for...

Magnetic forces
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them. In this lesson we take a look at m...

Electrostatic forces
Electrostatic forces are non-contact forces; they pull or push on objects without touching them.We take a look at the forces that exists between objects that are charged. We also revise some concept son static electricity form grade 8.
