gravitational force is a force that can act at a distance from an object. Gravitational force is the force of attraction between things and he earth.
Effect of Gravitational force:
Gravitational force is acting on us and all other object all the time.It is because of Gravitational force that we are able to stand on the ground and not float away . Gravitational force also has many other effects.
WHAT IS FRICTIONAL FORCE?
frictional force is a force that opposes motion. It is produced when 2 surface rub against each other.
effect of frictional force:
-slows down and stops object
-prevent an object form starting to move
-affect the movement of object on different surface.
gravitational force pulls all object downward and causes object have weight
frictional force which opposes motion and includes air and water resistance.
frictional force have many effects and can be useful or causes problem which can overcome by using lubricants or rollers and wheels.
