Energy Flashcards
Joules
Energy is measured in units called joules.
Potential energy
This is stored energy that is just waiting to do work such as a coiled spring or elastic band.
Kinetic Energy
The energy that moving things have ie, a windmill turning or a car moving.
Heat Energy

Light Energy
Light can move things in a crooked radiometer or in a solar powered calculator.

Wind can turn windmills which generate electricity.
Wave energy
The movement of large floats by the energy in waves could be used to generate electricity.
Biomass energy
