Question | Answer |
ability to do work or cause a change | energy |
energy due to motion | kinetic energy |
energy that is not causing any changes now, but could cause changes in the future. | Potential Energy |
energy that travels through space in the form of light and other types of energy. | electromagnetic radiation |
the total of all the kinetic and potential energy of the atoms in an object. | thermal energy |
transfer of thermal energy between objects that are in contact. | conduction |
the movement of warm liquids or gases to cooler areas. | convection |
three ways that heat moves | conduction, convection and radiation |
movement of energy by electromagnetic waves | radiation |
bends light light rays to make objects look larger. Thickest in the middle. | convex lens |
thinner in the middle than the edges, It can bend light rays to make an object look smaller. | concave lens |
bouncing of light or wave from a surface. ex: mirror...light still moves in a straight line. | refelction |
bending of light or waves as it passes from one material to another. ex: when light enters a prism | refraction |
sound moves slowest through what materials | areas of dry and cool air. |
sound waves move fastest through what materials | through hot substances |
what happens when sound waves in air hit a surface such as a wall or cliff? | some of the waves bounce or reflect back = echo |
sound is a wave of vibrations that spreads from its source. | sound energy |
how do sound waves travel | crests and frequency |
sound is measured through what? | decibels |
When an object has its greatest potential energy? | stretched rubber band, match box cars positioned on a track, hanging metal ball. |
When is nuclear energy released? | when a proton is knocked out of an atoms nucleus. |
