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

Question

Philoid · Accepted Answer

• Because of the friction, if the wheel B is brought into spinning, it will gain kinetic energy leads to an increase in mechanical energy.

• Due to friction heat will be generated which will lead to an increase in all energies.

• Internal energy is increasing due to a rise in temperature.
