Types of Energy
A rolling ball hitting a still ball
Motion (collisions) energy
Lamp
Starts out as electrical energy ends up as light energy and heat energy.
Battery
Gives energy to the circuit.
Non renewable resources
Fossil fuels or things found in the earth that are used for electricity/fuel and cannot be replaced.
Oil, natural gas
Sunlight
Clean, renewable
Sun isn't out at night and rainy periods
What is an example of sound energy?
Radio, buzzer, bell, horn
A loud noise makes rice grains move
Sound energy
