A spinning wheel is brought in contact with an identical wheel spinning identical speed. The wheels slow down under the action of friction. Which of the following energies of the frist wheel decrease.

A Spinning wheel A is brought in contact with another wheel, B initially at rest. Becouse of the friction at contact, the second wheel also starts spinning. Which of the following energies of the wheel B increase?

Give two methods by which friction is reduced in the wheels of the car.

Cae wheels often spin on icy roads. Explain why.

Draw the diagram of a spinning wheel.

A wheel of radius R is trapped in a mud pit and spinning. As the wheel is spinning , it splashes mud blobs with initial speed u from various points on its circumference . the maximum height from the center of the wheel , to which mud blob can reach is
