science sol 5.2- forms of energy
central idea: energy can occur in different forms, it can be transformed from one form to another, but it cannot be created or destroyed.
energy is the ability to cause change or do work. energy can be transferred in various ways and between objects.
types of energy
| electrical energy | mechanical energy | radiant (light) energy | thermal (heat) energy | sound energy |
|---|---|---|---|---|
| (image of an electrical outlet and plug) | (image of a car) | (image of a traffic light) | (image of a toaster oven with heat lines) | (image of a microphone) |
| computer, vacuum, air conditioning | hitting a ball, rowing a boat, using a screwdriver | solar panels, flashlights, x - rays | toaster oven, fire in fire pit, heat from the sun | balloon popping, music, echolocation |
energy transformations
energy cannot be created or destroyed; however, it can transform from one form into another to do work. (work means when a force acts upon an object, it causes that object to move in the direction of the force.) energy can take many forms such as thermal, radiant, sound, mechanical, and electrical.
energy can be moved from place to place by moving objects, or through sound, light, or electric currents.
energy can change forms but cannot be created or destroyed. if a stove is turned on, the electrical energy transforms into thermal energy. that thermal energy did not just appear out of nowhere, and the electrical energy did not just disappear.
here are some other examples of energy transformations:
| object | start | end |
|---|---|---|
| tea kettle whistling | thermal | sound |
| using a blender | electrical | mechanical |
