| Question | Answer |
|---|---|
| Energy is not a _____ | thing |
| ability to do work or cause change | energy |
| Unit for all types of energy | Joule (J) |
| Result of force applied over a distance. (F*D) ____=Force * distance | work |
| Stored energy do to position or condition | potential energy |
| Potential energy do to the position of an object above the earth | Gravitational Potential energy (GPE) |
| Kinetic energy is causing what? | change in position |
| Energy of motion | Kinetic |
| Type of mechanical energy from an object that can stretch or compress. | Elastic PE |
| _____ energy can be both potential and kinetic | Mechanical |
| Involves movement of matter, usually visible. You can see it at work. | Mechanical energy |
| The sum of the KE of all the particles of an object | Thermal Energy |
| Movement of thermal energy in and out of a system is | heat |
| You measure thermal energy by measuring changes in | temperature |
| Faster movement of particles means ____ heat and _____ energy | more |
| Thermal energy is a type of _____ energy | kinetic |
| Heat is not the same thing as | thermal energy |
| Acoustic energy is kinetic and is the transmission of energy by a | wave |
| This energy type involves back and forth motion | acoustic |
| Back and for motion refers to _____ motion | periodic |
| This type of energy is the ability to do work through the influence of a magnetic field. | Magnetic |
| Magnetic energy is created by the attraction and repulsion of N and S | poles |
| Any object that is conducting electricity also generates a | magnetic field |
| Electromagnetic waves radiated by matter. | Radiant energy |
| Radiant energy is generated by causing an | electromagnetic field |
| Radiant energy is the only kind of energy that can travel through a | vacuum |
| Radiant energy is the only energy that reaches earth from the | sun |
| These are examples of electromagnetic energy (EM energy) | light waves |
| Potential energy stored in chemical bonds | chemical |
| Chemical energy is released when _____ breaks | bonds |
| Example of chemical, potential energy | food |
| Example of electrical energy | battery |
| Example of mechanical energy | baseball moving |
| Potential energy stored in the atom's nucleus | nuclear |
| combining two nuclei | fusion |
| splitting a large nucleus | fission |
| Fiss... | apart |
| Example of nuclear PE/KE energy | nuclear bombs |
| fuse... | together |
| Energy found in matter | mass |
| Mass energy is the _____ source of potential energy | greatest |
| Thermal energy and ____ are NOT the same thing. | heat |
| In E=mc^2 the c stands for the | speed of light |
| Which has greater GPE, a boy on top of a car or a boy on top of a house. | boy on the house |
| Energy can never be created nor destroyed, only changed from one form to another | Law of Conservation of Energy |
| The total energy entering the process equals the total energy that exists at the end of the process. | Third Law of Thermodynamics |
| Energy In = | Energy out |
| The amount of usuable energy produced divided by the amount of energy available before transformation | efficiency |
| The position from which the distance is measured. (Example: height measured from the ground to the roof.) | zero reference point |
| Decrease thermal energy is | cooling |
| Gaining of thermal energy is | heating |
| Acoustic energy is transmitted through | particle oscillations |
| Particle oscillations are small | vibrations |
| Electrical energy is caused by the lack, excess, or movement of | electrons |
| Radiant energy ______ need matter to travel | does not |
