Energy Forms
The energy of motion
Kinetic energy
Photosynthesis
Light (electromagnetic) --> Chemical
The three temperature scales used to measure heat.
Fahrenheit, Celsius, and Kelvin.
Word for the measure of a wave from one crest to the next.
Wave length
What force causes object to fall down?
(The reason objects have potential energy)
Gravity.
The energy of position (either gravitational or elastic)
Potential energy
Strike & light a match
Kinetic/Chemical --> Light (electromagnetic) & Heat
The state of matter with the greatest thermal energy.
Gas
Using a slinky, demonstrate both a transverse wave (electromagnetic) AND a longitudinal wave (sound).
[demonstrate]
Where is the point of greatest kinetic energy?
Label...
Electromagnetic
Car
Chemical --> Kinetic, sound, light (electromagnetic), thermal (or electrical)
An example of conduction.
Answers may vary.
Word measure of how many wave lengths occur in a period of time.
Frequency
True or False: All potential energy converts immediately to kinetic energy when an object starts to fall down.
False. Potential energy converts to kinetic energy gradually.
Energy that is the random vibration of molecules.
Heat
Give an example of chemical to mechanical energy.
Answers will vary.
True or False: all objects emit radiation/electromagnetic energy.
True.
Measure of a wave from resting point to crest.
Amplitude
Which slinky has greater potential elastic energy?
The more stretched one.
Sound.
Give an example of electric to thermal energy.
Answers will vary.
What is convection?
Method of heat transfer in fluids where warmer fluid rises and colder fluid sinks.
Which wave has more energy (vary frequency)?
Higher frequency
What is the word for when two objects rub together, generating heat? It is the main reason for heat loss in the transformation from potential to kinetic energy.
Friction.
