Energy Transformations Notes

Energy is lost during every transfer.

Energy is created during transformations.

Energy is conserved and only changes form.

Energy is destroyed in some processes.

It increases.

It decreases.

It remains the same.

It disappears.

Energy transfer is when energy moves from one place to another, while energy transformation is when energy changes from one form to another.

Energy transfer is when energy changes from one form to another, while energy transformation is when energy moves from one place to another.

Energy transfer and energy transformation are the same thing.

Energy transfer only happens in living things.
