Question

what is frictional force ??​

Answer 1

Answer:

Friction is the force that opposes motion between any surfaces that are in contact.

There are four types of friction: static, sliding, rolling, and fluid friction (Air/Viscous friction). Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.

Answer 2

Answer:

Frictional force is the opposing force that is created between two surfaces that try to move in the same direction or that try to move in opposite directions. The main purpose of a frictional force is to create resistance to the motion of one surface over the other surface
