Question

The force of friction is maximum when the surface
a.Is on the point of motion
b.is at rest
c.Is moving
d.the friction remains same at all points​

Answer 1

The force of friction is maximum when the surface

a. Is on the point of motion

Answer 2

The force of friction is maximum when the surface is on the point of motion.

• There are two friction: Kinetic friction and static friction.

       Static friction acts when the body is at rest and Kinetic friction acts when

        the body is in motion.

• The coefficient of static friction is slightly more than the kinetic friction.

• When the body is just about to move the frictional force becomes maximum.
