What does the conservation of energy say?

Answer 1

That the total amount of energy in a closed system doesn't change.

Answer 2

The law of conservation of energy states that energy is never created or destroyed only converted.

This law is known by two different names:

1. "The Law of Conservation of Energy"

2. "The First Law of Thermodynamics"

Answer:Conservation of energy means that the total amount of energy in a closed system remains constant. You can't create energy out of nothing, and you can't destroy it - however, you can convert from one type of energy to another. This includes converting useful energy to unusable energy - but the total amount of energy still remains constant.

There is a quantity called energy that is conserved in a closed system. That is to say, if no energy get into a system or gets out, the total amount of energy will remain constant.

Energy can neither be created nor destroyed

Answer 3

That basically means that there is a quantity called energy, and that the total amount of energy in the Universe (or in any closed system) doesn't change over time. You can't create or destroy energy.

Answer 4

That the total energy in a closed system will neither increase nor decrease.

Answer 5

When one form of energy is transformed to another, no energy is destroyed or created in the process.

Answer 6

The law of conservation of energy states that energy can neither be created or destroyed. Energy can only be transferred or transformed into other forms.

Answer 7

Energy can neiter be created nor destroyed.

Answer 8

A law of conservation means there is something - in this case, the amount of energy - that remains constant over time.

Answer 9

The law of consrevation of energy states that NO energy can be lost or gained, it can only change from one kind (e.g. kinetic or electric) into another kind of energy (e.g. potential or heat)

Answer 10

Conservation of energy says that Mass-Energy can not be created nor destroyed.
