Mechanical energy that has been lost to friction has actually been destroyed?

Nope. One of the strongest pillars of Physics is the fact that energy is never
destroyed. Energy lost to friction is no longer available to do the job that
you happen to need it for, but it's still there, and it shows up as heat.

Mechanical energy that has been 'lost' to friction has actually been destroyed?
false apex
If Mechanical energy that has been lost to friction has actually been destroyed true or false?
False
Friction doesn't convert energy if actually destroys it true or false?
Not QUITE true. Friction can convert usable energy in useless (or unusable) energy, but energy itself can't be destroyed.
Explain the role of friction has in the energy transformation of a person skiing downhill?
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. ur welcome. you have to give me 5 bucks.
Why does the mechanical (total) energy of the skater not change over time?
It certainly does; mechanical energy will be wasted due to friction. Otherwise, if you disregard friction, the fact that the total mechanical energy is conserved follows from conservation of energy.
Mechanical energy is converted into heat energy when?
... friction occurs.
What force opposes mechanical energy?
friction
Can an objects mechanical energy change?
Yes, it can. For instance, if you have friction in the system mechanical energy of the system is not conserved.
Does friction causes mechanical energy to be transformed into potential energy?
Thermal
How does friction affect perpetual motion machines?
IN SIMPLE WORDS: Friction turns mechanical energy into heat energy which causes a loss in mechanical energy and loss in possibility to continue motion..
What is the law of conservation of mechanical energy?
The law of energy conservation states that, in a closed system, the amount of energy never changes. It stems from the classical physics principle that, while energy can be converted from one form to another (from kinetic energy (motion) to thermal energy (heat), for example) energy can neither be created nor destroyed..Since the different forms of energy are interchangable (kinetic to heat, for example), there is no law of conservation of mechanical energy as such. But in a hypothetical system without friction, air resistance, chemical reactions, etc, mechanical energy could be conserved.
Friction causes mechanical energy to be transformed into what?
Heat.
