|
|
light waves |
wavelengths that are visible to most human eyes |
|
|
radio waves |
type of electromagnetic with wavelengths in the electromagnetic spectrum longer than the infrared light |
|
|
theory electromagnetism |
electromagnetism the is the study of the electromagnetic force |
|
|
Nuclear Energy |
energy stored in the nucleus of atoms |
|
|
nuclear fission |
nuclear reaction when massive nucleus splits into smaller nuclei |
|
|
equation for nuclear energy |
2 E=mc E= total amount of energy 2 M= mass C =velocity of light |
|
|
entropy |
measurement of disorder. lower entropy= less disorder high entropy= high disorder |
|
|
elastic energy |
energy stored in elastic materials, stretching or compressing an object. Equation- PE=0 PE= 1/2kx2 |
|
|
thermal energy |
related to the temperature in an object, measured in joules |
|
|
joule |
measurement of energy |
|
|
specific heat |
amount of heat per unit mass required to raise the temperature by one degree celcius |
|
|
Equation of thermal energy |
Q=mcΔT m= mass Q= thermal energy C= specific heat Δ=temperature change |
|
|
conduction |
occurs when a substance is heated, particles will gain more energy and vibrate more |
|
|
convection |
Occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas |
|
|
Radiation |
Method of heat transfer that does not rely on any contact between the heat source and the heated object |
|
|
Thermodynamics |
Branch of physical science that deals with the relations between heat and other forms of energy. (mechanical, electrical, or chemical energy |
|
|
1st thermodynamic law |
Energy cannot be created or destroyed |
|
|
2nd thermodynamic law |
Entropy of any isolated system not in thermal equilibrium almost always increases |
|
|
conductor |
It conducts electricity, allows energy to flow by |
|
|
Insulator |
Does not conduct electricity, blocks energy from passing |
|
|
chemical energy |
Stored in the bonds of chemical compounds |
|
|
Endothermic |
absorbs energy as heat |
|
|
exothermic |
releases energy as heat, light, or sound |
|
|
fossil fuels |
organic materials formed from decaying organisms that have to oil, coal, and natural gas by heat and pressure |
|
|
Electrical energy |
an electrical charge that can neither be created or destroyed |
|
|
conservation of charge |
the principle that an electrical charge can neither be created or destroyed |
|
|
wave |
traveling disturbance that travels through space and matter transferring energy from one form to another |
|
|
type of wave |
mechanical waves Electromagnetic waves |
|
|
mechanical wave |
wave that passes through a medium which means it requires some sort of matter. only travels through matter |
|
|
electromagnetic waves |
wave that travel through a vacuum or an empty space. |
|
|
transverse waves |
transverse waves were the disturbance moves perpendicular to the direction of the wave |
|
|
compressional waves |
waves that move in the same direction of the disturbance |
|
|
wavelength |
is the distance successive crest of a wave especially points in a scum of electromagnetic wave |
|
|
frequency |
number of cycles that are completed in a certaiscin time |
|
|
period |
the time it takes for one water molecule to move up, move back down, & then returns to its original positions |
|
|
amplitude |
the distance between the mid-line of a wave and its crest or trough; measures how much energy is being transported by the wave |
|
|
wave speed |
the speed is the distance traveled by a given interval of time |
|
|
heat |
thermal energy that flaws from something at a higher temperature can do work |
|
|
temperature |
measure of the average kinetic energy of the particles |
