Question

explain with one example that frictional force is proportional to the normal force?

Answer 1

The example that satisfy the statement is given below.

• The normal force is the perpendicular force acting on the body or mass which is sliding to downwards or moving upward.

• The frictional force is the opposite force which is acting opposite to the force the in which the body is moving.

• The normal force is always perpendicular to the frictional force.

• The example can be any body which is sliding or on the inclined plane. Like when we go to inclined planes.

• We push our body in forward direction so that we can move forward otherwise due to the gravity behind will push backward.

• Here the normal is acting upward to maintain the motion.
