Question

State whether the given statement is true or false :

Gravity and friction are both contact forces.

• A. True
• B. False

Answer 1

The correct option is B False

Answer is B.

The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth.
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are two types of frictional force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.
Hence, gravity is a non-contact force and friction is a contact force.
