Is friction a way to produce heat energy?
Yes. Whenever energy is wasted through friction, most of this wasted energy is converted to heat.
What is the wasted energy from a rocket?
The wasted energy in a car is electrical energy
What type of energy is created by friction?
Energy wasted due to friction is converted mostly to heat.
When energy is released when friction is applied?
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.
Why does a saw become warm when it is used to cut a log of wood. State the energy transformation taking place?
Mechanical energy is wasted due to friction. The wasted energy is converted into heat.

When an object loses kinetic energy due to a force of kinetic friction is the loss of kinetic energy transformed primarily into potential or thermal energy?
Kinetic friction is associated with thermal energy (and sound or light).

Mechanical energy is wasted due to friction. The wasted energy is converted into heat.
How can you make machines more efficient?
Reduce or remove friction. Ensure that the energy going in is not wasted due to unnecessary work or heat.
What are two ways friction isn't useful?
1) Friction tends to waste energy.2) The wasted energy gets converted into heat, which may be harmful in some cases - or special measures may have to be taken, to get rid of such waste heat.
Why is a the mechanical efficiancy of a machine less than 100?
Because, due to friction, there will always be a percentage of the energy lost through wasted heat.
Why not all potential energy is converted to kinetic energy in roller coaster?
Because some of it is converted into heat due to friction.
Why Appliances only transfer part of the energy usefully?
It is inevitable that some energy is almost always wasted. For example, if there are moving parts, it is inevitable that energy is wasted through friction; or if there is a temperature difference, it is inevitable that heat gets transferred, etc.
Is heat little friction or is it great friction?
heat is really half of friction
