physics - energy
energy - correct answer ✔the ability to do work or cause a change.


forms of energy - correct answer ✔mechanical (moving parts of things), heat
(thermal), chemical (chemical bonds between atoms), electromagnetic (light)
nuclear, electrical, gravitational, elastic (stretching/compressing)


energy conversions - correct answer ✔energy can be changed or converted
from one form into another. Always come in pairs (one form into another)


mechanical energy - correct answer ✔any energy associated with motion of
moving objects. This is the energy of moving things, parts, or particles. Can
be simple as rolling a rock, hitting a nail with a hammer


heat (thermal) energy - correct answer ✔caused by internal motion of atoms
or molecules within a substance. often results from friction. particles move
faster as energy increases. so the faster the particles move, the more energy
they carry.


chemical energy - correct answer ✔energy is released when the bonds
between atoms or molecules are broken. chemicals may contain huge
amounts of potential energy.


electromagnetic energy (light) - correct answer ✔results from any
wavelength of light, whether it is visible or not. ex.) xrays, lasers, radio waves


electrical energy - correct answer ✔caused by the movement of electrons or
charged particles. often call this electricity. ex.) electricity flowing in our home
wiring or batteries
