Question

The minimum amount of force required to overcome the force of friction is called _____

Static friction is also called __ friction

Friction depends on __ of surface in contact

The static frictional force is a __ force​

Answer 1

Answer:

when a body is in contact with another body and some normal force acts then if any force is applies on then which causes relative motion between them, a resisting force will act called frictional force. Up to a point when motion does not start the friction acting is called static friction, once the motion starts then resisting force acting slightly decreases [call dynamic friction force.

so the force required to overcome to start a motion is static frictional force.

Answer 2

Answer:

Force of friction is sometimes advantages and disadvantages

The use of lubricants
