Electrical energy | can flow through a circuit, it can produce thermal energy, light energy, sound energy and magnetic energy. |
Temperature | measures the thermal energy of an object |
Light energy | Travels through space in waves in a straight line, when it hits an object, it is either absorbed, transmitted, refracted(bent), or reflected |
Sound energy | is caused by vibration |
Changing the speed of vibrations | will change the pitch of the sound |
Sound energy can be | absorbed, transmitted, or reflected |
Thermal energy can be increased by | heating |
A battery | uses chemical energy to make electric energy |
Photosynthesis | solar energy is converted to chemical energy |
Thermal energy is also known as | heat energy |
