Solution

The correct option is A
True

When the two wheels come into contact with each other, friction between them opposes the relative motion and wheel B also starts to rotate, increasing its mechanical energy and some of the energy is lost as heat.

A spinning wheel A is brought in contact with another wheel B which is initially at rest. Because of the friction at contact, the second wheel also starts spinning, then which of the following energies of B won't change?

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

A uniform wheel of radius R is set into rotation about its axis at an angular speed $ω$ . This rotating wheel is now placed on a rough horizontal surface with its axis horizontal. Because of friction at the contact, the wheel accelerates forward and its rotation decelerates till the wheel starts pure rolling on the surface. Find the linear speed of the wheel after it starts pure rolling.
