Gravitational and Frictional forces

GRAVITATIONAL FORCE

Gravitational Force is the force between the things and the Earth. It always pull things down to the center of the earth. The power of the gravitational force is not the same everywhere.Some examples are when swimmer dives, man climbing the rocks and speeding up a skier.

 FRICTIONAL FORCES
Frictional force is a force that produces friction. It is produced when two surfaces rub each other. Frictional Forces can slow down and stop moving objects, prevent an object to move and affect the movement of object in different surfaces. Examples of Frictional Force is when you push a toy car, it will slow done and stops.
