How does friction change the energy in a machine?

Answer 1

Well i think friction and air resistance cause some of the mechanical energy of an object to change to thermal energy so the mechanical energy of the object is not destroyed. Rather, it is transformed into thermal energy. the total amount of energy always stays the same. <3 Tayler

Answer 2

its affects it by when friction and the energy coversion for a example thermal energy and friction goes against each other then it creates friction that what affects energy conversions.

Answer 3

I'm not exactly sure what you are asking about, but I'll give it a go anyway.

When two objects rub together during motion, friction causes some heat to be produced. This energy is removed from the kinetic energy of the objects, causing the velocity and acceleration to be affected. This means that the velocity of the objects is likely to be lower than predicted.

Answer 4

The movement of a moving object - its kinetic energy - decreases; the energy gets converted into heat, that is, it is wasted, since you can't convert all of the heat back into other types of energy.

Answer 5

Friction dissipates energy. It may heat the machine or its surroundings, and

it's always responsible for the machine's efficiency being less than 100% . . .

you always get less energy out of a machine than you put into it.

Answer 6

it would affect it by allowing the potential energy to never drop even as kinetic energy goes up.

Answer 7

If you mean mechanical advantage, the more friction a system creates, the lower the mechanical advantage

Answer 8

Friction is a force which works to oppose (or to slow the movement caused by) the kinetic energy of an object.

Answer 9

look in a text book.
