Units 6 & 7
UNITS 6 & 7 VOCAB DEFINITIONS #1
| Term | Definition |
|---|---|
| Energy | is the ability to do work and cause a change in matter. |
| Kinetic energy | is energy of motion/action |
| Potential energy | it is stored energy (not in motion). Energy an object has due to its position or condition, it is not causing a change or doing work but it has the potential to do it. |
| Gravitational Potential Energy | A form of potential energy (not in motion) that is waiting for gravity to pull an object down. |
| Elastic potential energy | A form of potential energy that involves stretching and retaining its shape. |
| Light Energy | form of energy you can see; Energy that is made of electromagnetic radiation that travels in waves. Light travels fastest through gases, slower through liquids, and slowest through some solids. |
| Waves | Energy travels in waves. |
| Thermal (Heat) energy | energy of moving particles of matter from warmer cooler areas. Energy that is the total of all the kinetic and potential energy of atoms. |
| Thermometer | a tool to measure the amount of thermal energy. |
| Conduction | is the transfer of heat between objects that are touching. Frying eggs, bacon, sausage in pan |
| Convection | is the transfer of thermal energy (heat) in moving liquids or gases in a circular motion. Exam: convection currents in water & air; air conditioning, heater; cooking anything in water- pasta, boiling eggs |
| Radiation | is the transfer of heat that flows through the air by electromagnetic waves. Exam: sun’s rays to Earth; toaster, microwaves |
| Chemical energy | Potential energy that is the energy of electrons that form bonds between atoms energy that can be released by a chemical reaction. Some examples are: food, fuels, a match, batteries and fireworks. |
| Nuclear energy | is potential energy found in the nucleus of the atom by releasing protons (p+) |
| Sound energy | energy that travels as waves through vibrating matter. Sound travels through solids fastest, liquids slower, and gases the slowest. |
| Mechanical energy | the total energy of motion & position of an object; energy that involves moving parts. Exam: machines, watches, clock, computers, rides, cars, pens, sharpeners |
| Electrical energy | energy caused by the movement of electric charges. |
| Static electricity | the buildup of charges that are positive and cause hair to stand out. |
| Electric current | the flow of charges- electrons (e-) |
| Electromagnet | a magnet that has an electrical current running through it. |
| Generator | device that converts kinetic energy to electrical energy. |
| Electric motor | device that converts electrical energy into mechanical energy |
