## Newton’s Second Law of motion, Newton’s Third Law, Factors that affect the acting force & the acceleration

It is preferable to use air bags in the cars to protect the driver during accident , The colliding of a large truck with wall is more destructive than the colliding of a small...

## Factors affecting the friction between the solid objects and the water

When any object moves through the water (such as the fish, the swimmer, the dolphin, and the ship), there is a friction force arises between this object and the water which is called water...

## The friction between the solid objects and the air

When a solid object moves in the air, a friction force arises between the object and the air, This type of friction is called the air resistance and it acts in the opposite direction...

## Factors affecting the friction between two solid objects

Friction arises when two solid objects touch each other, When the friction force is larger than the movement force, the body does not move, when the friction force is smaller than the movement force,...
