Energy Vocabulary
Energy vocabulary for 6th grade science
| Term | Definition |
|---|---|
| Conduction | the transfer of heat by objects touching or particles withing objects touching |
| convection | the transfer of heat by the movement of fluids (liquids and gases) |
| radiation | the transfer of heat by electromagnet waves |
| inclined plane | a sloping surface, like a ramp, that reduces the force required to move an object |
| lever | a rigid bar or board that is free to move around a fixed point called a fulcrum that reduces the force needed to lift an object |
| pulley | a grooved wheel with a rope running along the groove that can change the amount of force needed to move an object or the direction of the force |
| simple machine | a device that helps reduce the force required to do work |
| work | when force is applied over a distance to move an object: work =force X distance |
| scissors and crow bar | examples of tools that are levers with the fulcrum in the center of the lever arm |
| tweezers, broom, wheel barrow, bottle opener | examples of tools that have the fulcrum on the end of the lever arm |
| block and tackle system | type of pulley system |
| wedge | one or two back-to-back inclined planes |
| screw | inclined plane wound around a post or cylinder |
| wheel and axle | two circular objects: a central shaft inserted through the middle of a wheel |
| door knob, steering wheel, screwdriver, and gears | examples of wheel and axle |
| complex machine (compound machine) | consisits of two or more simple machines |
| heat energy | the transfer of thermal energy (energy associated with the motion of the particles of a substance) |
| solar energy | energy from the sun |
| chemical energy | energy stored in particles of matter |
| electrical energy | energy flowing in an electric circuit |
| mechanical energy | energy due to the motion and position of an object |
| kinetic energy | energy an object has due to its motion |
| mechanical potential energy | energy related to the position of an object |
