do not let any light pass through them | opaque |
objects let some light through, but not all light | translucent |
lenses refract light and make objects look larger | convex |
lenses refract light and make objects look smaller | concave |
does not allow thermal energy to pass through them easily | insulators |
allow thermal energy to pass through them easily | conductor |
energy that is stored in an object, not in motion, but capable of moving, a parked car on hill, a coiled spring, charged battery | potential energy |
energy possessed by a body because of its motion, car going down a hill, bowling ball striking pins | kinetic energy |
energy of motion | mechanical |
also known as heat energy | thermal energy |
energy produced when an object vibrates | sound energy |
you hear because what vibrates | eardrum |
travels in a straight line | light |
the average speed of particles in a substance, measured in Celsius or farenheit | temperature |
form of energy that travels in waves and can move through empty space where there is no air | light energy |
