Energy and Energy Transformations Mrs. Knicely
Potential Energy • Potential Energy- energy that a piece of matter has because of its position or because of the arrangement of parts
Kinetic Energy • Kinetic Energy- energy that is involved with motion • ANYTHING that involves with motion has kinetic energy
Electrical Energy • Electrical Energy- moving electric charges • Electrical energy is very important in our everyday life. There are electric charges everywhere you go!!
Chemical Energy • Chemical Energy- energy that has anything to do with chemicals • When you put certain chemicals together and they make an explosion, that is chemical energy
Sound Energy • Sound Energy- anything that has to do with sound has sound energy • For example, when you hit a tuning hammer on something it will make a sound. That has sound energy.
Elastic Energy • Elastic Energy- anything that stretches or has a spring • Thing like rubber bands, trampolines, and even your muscles have elastic energy!!
Solar Energy • Solar Energy- energy that comes from the sun
Magnetic Energy • Magnetic Energy- energy generated due to magnetic field
Potential Energy transforming to Kinetic Energy • When energy changes from kinetic to potential, that means the object was at rest but now it moving.
