It can mostly be changed into Electrical Energy.
Some energy is changed to unusable energy. Usually this is in the form of waste heat.
Some of the energy will usually be converted into an unusable form of energy, often as heat.

It's mostly converted to heat. Some of it can be used for the physical work of wearing down the surfaces causing the friction, depending on the hardness of the surfaces and their friction coefficient.
The energy of the swinging is converted into heat energy by friction.
friction creates heat. Largely heat, which comes from the external agent energy causing the friction. Also some possible rearrangement of the atomic/molecular structure of the surface, and the energy for that also comes from the external agent.
Some of the energy has converted into heat energy because of the friction, the kinetic energy is gone, but there is potential energy. Also, some of the energy has converted into sound energy from the basketball bouncing. Your friend is wrong because there is still energy like kinetic energy, energy cannot disappear it gets converted.
In many energy conversions, some energy gets lost - in some cases through friction. Of course, according to the Law of Conservation of Energy, energy can't really diseappear, but it does get converted into low-value forms, i.e., unusable energy.
Kinetic energy is used to overcome friction and is dispersed as heat; some energy is converted to sound.
Kinetic Energy.
Yes, that is correct.
Because some of it is converted into heat due to friction.
Some of the energy is converted from the motion of the bodies to sound and heat when it is used to overcome friction between the two bodies.

Friction
Before it rolls downhill, it has gravitational potential energy. As it rolls downhill, part of this potential energy is converted into kinetic energy (including rotational energy); due to friction, this will soon be converted into waste energy, mainly heat.
When you give your dog energy bites it keeps he/she stronger and with a better heart.

Yes, some work is converted into heat due to the friction.
