Asked by Nico
1000 joules of energy are put into a pulley system, and 400 joules come out. What does the Law of Conservation of Energy imply about the lost energy?(1 point)
Responses
The lost energy is caused by friction.
The lost energy is caused by friction.
The lost energy is not truly lost, but it changed into a different form.

Correct answer: "The lost energy is not truly lost, but it changed into a different form."
Explanation: By conservation of energy, the 600 J difference was converted into other forms (typically thermal energy due to friction, sound, etc.), not destroyed.
