Question

which example does friction act in the direction of forward motion of the object on which it acts​

Answer 1

Answer:

For example.

1. When a person pushes the ground backwards (action), the rough surface of ground reacts and exerts a forward force due to friction–which causes the motion. Without friction, person would slip and shall not be able to move.

2. In cycling, rear wheel moves by the force communicated to it by pedaling, while front wheel moves by itself.
