Answer 1

Answer:

friction is a force which is applied on an object due to irregular surface. if there was no friction or drag then a moving object will continue to move forever. therefore friction stops the nation of an object.

FRICTION IS A CAUSE OF MOTION---~

It is a general misconception that friction always opposes the motion. No doubt, friction opposes the motion of a moving body but in many cases it is also the cause of motion.

FOR EXAMPLE ---~

(1.) WHILE WALKING, A person aur vehicle pushes the ground backwards (action) andhraboxoffice off The ground reacts and exerts a forward forced into fraction which caused the motion. if there had been no friction there will be slipping and no motion.

(2.) DURING CYCLING THE rear wheel moves by the force communicated to it by pedalling while front wheel moves by itself. So, when pedalling a bicycle , the force exerted by rear wheel on ground makes force of friction act on it in the forward direction (like walking). Front wheel moving by itself experience force of friction in backward direction (like rolling a ball).

However, if pedalling is stopped both wheels move by themselves and so experience force of friction in backward direction.

(3.) if a body is placed in a vehicle which is accelerating the forces of friction is the cause of motion of the body along with the vehicles(i.e., the body will remain at rest in the accelerating vehicle until ma < μs mg ). if there had been no friction between body and vehicle, the body will not move along with the vehicle.

From these examples it is clear that without friction, motion cannot be started, stopped, or transferred from one body to the other.
