Energy Types
Energy that involves movement
What is kinetic energy?
Provides power to charge electrons, usually in the form of a battery
What is a power supply?
Energy that stays the same once moving from one object to another
What is energy transfer?
a measure of how much input energy is transformed into useful output energy.
What is efficiency?
Diver jumping off a diving board
Gravitational potential energy -> translational kinetic energy
Energy that is stored for later use
What is potential energy?
The component of an electrical circuit that transforms energy from electrical to intended energy
What is a load?
Energy that moves from one form to another?
What is energy transformation?
Energy is measured in joules
Lighting a torch
Chemical energy -> light energy
Energy that is stored inside the nucleus of an atom
What is nuclear energy?
Wires allow for a current of charged electrons to flow
What is a conducting path?
The type of energy at the beginning of an energy flow diagram
What is input energy?
Energy cannot be created or destroyed, but it can be transferred or transformed from one from to another
What is the law of conservation of energy?
Fireworks going off
Chemical energy -> light energy
-> sound energy
-> heat energy
Energy that stores as an object increases its vertical distance?
What is gravitational potential energy?
The moving of charged electron particles through a circuit
What is electricity?
The type of energy at the end of an energy flow diagram
What is output energy?
Energy that is intended to be used
a cricket bat making contact with a cricket ball
Translational kinetic -> translational kinetic
Wasted energy - sound and heat
Energy that we can physically see moving
What is translational kinetic energy?
A measure of how much energy is provided to the electrons
What is voltage?
Sound energy in a hairdryer
What is wasted energy or energy byproducts?
Energy that is "left over" once transformation occurs.
What is energy byproduct or wasted energy?
Heating your hand by holding a warm mug
Thermal energy -> thermal energy
