Force Motion, Energy


Energy the ability to do work
Light Energy energy that is carried in light waves; one primary source is the sun
Sound Energy energy that is caused by vibrations and travels through the air in waves
Thermal Energy energy that is the random motion of molecules (measured by temperature…the faster the molecules move, the hotter something is).
Electrical Energy energy that is powered by a form of electricity, such as a battery or a wall socket
Mechanical Energy energy of movement
Potential Energy non-moving energy (ex. stretched elastic, chemicals such as batteries, etc.)
Kinetic Energy moving energy (ex. light, sound, electrical, mechanical, etc.)
Circuit a path through which electrical currents (electricity) flows
Parallel Circuit an electrical current that has more than one path that it can travel on
Series Circuit an electrical current that travels in one path
Conductor a substance that easily carries the flow of electrons
Insulator any material that will not carry the flow of electricity, an example is a rubber cover on a wire protecting you against an electrical shock
Reflection the bouncing of light from a surface
Refraction light traveling through an object causing it to slow down and bend
Transparent easy to see through (clear)
Translucent only allows some light to flow through; not clear
Opaque no light is let through (can’t see through it at all)
Force a push or pull that causes an object to move, stop, or change direction
Gravitation the force that pulls all objects in the universe toward one another
Friction a force that opposes, or acts against, motion when two surfaces rub against each other
Magnetism the force of repulsion (pushing) or attraction (pulling) between poles of magnets
