P1.6 Flashcards
What are the nine types of energy
Thermal, light, electrical, kinetic, elastic potential, sound, nuclear potential, gravitational potential
What is gravitational potential energy
Energy stored in things that gets released once the object falls
What is nuclear potential energy
Energy stored in the nuclei of atoms
What is chemical potential energy
Energy stored in chemicals such as fuel and batteries
What happens in energy transfer
Energy is transferred from one form to another but no energy is lost
What is an energy conservation diagram
A diagram showing how energy is transferred. It has arrows coming of the main arrow showing how energy is lost. The thickness of the arrows show how much energy it represents
What is the energy efficiency equation
Efficiency = useful energy transferred by device / total energy supplied to the device * 100
