The wheel shown is fixed at 'O' and is in contact with a rough surface as
shown. The wheel rotates with an angular velocity e What is the direction
and nature of friction force on the wheel and on the ground.
-rough surface
Answers
E = s/rt will be the the angular velocity e of the wheel that is rotating on the surface whereas s is the resistance traveled, D is the time taken while R is the radius of the wheel. Since the wheel is rotating, not sliding on a surface and the nature of friction acting on it would be rolling friction. The nature of this friction would always be less in amount, then the fraction that would have been offered when the wheel slides or the friction due to kinetic energy.
Answer:
Explanation:
The friction on wheel is forward If u take a an instataneous point at the bottom of the wheel then Rw is acting backwards which shows tendency of wheel to go backwards relative to ground and to oppose slipping f is forward so it is kinetic friction And on ground backward
