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 forces and how we can calculate the weight of an object. We also compare the weight of objects on different planets.

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.

An electrical conductor is a substance that allows an electrical current to pass through it and an insulator is a non-conducting material that does not carry any charge.We take a closer look at electrical cells and batteries as well as the different types of conductors that we find. We also take...
