        Help!  

Term
Definition
energy   the strength and vitality required for sustained physical or mental activity  
🗑
potential energy   the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.  
🗑
elastic potential energy   potential energy that is stored when a body is deformed  
🗑
kinetic energy   energy that a body possesses by virtue of being in motion  
🗑
gravitational potential energy   Gravitational energy is the potential energy associated with the gravitational field.  
🗑
mechanical energy   energy in a mechanical form  
🗑
thermal energy   Thermal energy is the part of the total potential energy and kinetic energy of an object or sample of matter that results in the system temperature.  
🗑
electrical energy   energy made available by the flow of electric charge through a conductor  
🗑
chemical energy   that part of the energy in a substance that can be released by a chemical reaction  
🗑
nuclear energy   the energy released during nuclear fission or fusion, esp. when used to generate electricity.  
🗑
electromagnetic energy   Radiant energy is the energy of electromagnetic waves  
🗑
energy transformation   Energy transformation or energy conversion is the process of changing one form of energy to another.  
🗑
law of conservation of energy   the fundamental principle of physics that the total energy of an isolated system is constant despite internal changes  
🗑
temperature   the degree or intensity of heat present in a substance or object  
🗑
absolute zero   the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal  
🗑
conduction   the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material  
🗑
convection   he movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat  
🗑
radition   the emission of energy as electromagnetic waves or as moving subatomic particles  
🗑
conductor   a person who directs the performance of an orchestra or choir  
🗑
insulator   a thing or substance used for insulation  
🗑
melting   make or become liquefied by heat  
🗑
freezing   the freezing point of water.  
🗑
evaporation   the process of becoming a vapor  
🗑
boiling   the action of bringing a liquid to the temperature at which it bubbles and turns to vapor.  
🗑
condensation   water that collects as droplets on a cold surface when humid air is in contact with it.  
🗑
thermal expansion   Thermal expansion is the tendency of matter to change in volume in response to a change in temperature  
🗑
law of universal gravition   inverse square law  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
