Energy:  a quantity that describes the ability of an object to change or cause changes.
 
Joule (J):  a unit of energy. One joule is enough energy to push with a force of 1 newton for a distance of 1 meter.
Pushing a 1-kilogram object with a force of 1 newton for a distance of 1 meter uses 1 joule of energy

Mechanical:  Energy a form of energy that is related to motion or position. 
Examples include potential and kinetic energy
 
Chemical Energy: a form of energy that is stored in molecules
 
Nuclear Energy: a form of energy that is stored in the nuclei of atoms.
 
Radiant Energy: a form of energy that is represented by the electromagnetic spectrum.

n physics, the word work has a very specific meaning. Work is the transfer of energy that results from applying a force over a distance. Work is a product of the force-applied times the distance traveled (work = force × distance)

The chemical energy (a fuel) is a gas called methane. It is burned in a chemical reaction and heat energy is released. The heat energy makes hot steam. The steam turns a device called a turbine, making mechanical energy. Finally, the turbine turns an electric generator, producing electrical energy. You can obtain this electrical energy by “plugging in” to an electrical outlet!]]> 2017-11-11 16:24:42 UTC https://padlet.com/marlonkantor/ex7twcpsld31/wish/205899840 Energy in Your Life marlonkantor https://padlet.com/marlonkantor/ex7twcpsld31/wish/205899949 A joule is a tiny amount of energy compared to what you use every day. One joule is just enough energy to lift a pint of ice cream 21 centimeters off the table. That same pint of ice cream releases 3 million times as much energy
when it is digested by your body! Some units of energy that are more appropriate for everyday use are the kilowatt-hour (kWh), food Calorie, andBritish thermal unit (Btu).

The total amount of energy in the universe is constant. ]]> 2017-11-11 16:30:24 UTC https://padlet.com/marlonkantor/ex7twcpsld31/wish/205900307 marlonkantor https://padlet.com/marlonkantor/ex7twcpsld31/wish/205900874 2017-11-11 16:36:44 UTC https://padlet.com/marlonkantor/ex7twcpsld31/wish/205900874 marlonkantor https://padlet.com/marlonkantor/ex7twcpsld31/wish/205901229 2017-11-11 16:40:50 UTC https://padlet.com/marlonkantor/ex7twcpsld31/wish/205901229 The Six Types of Energy marlonkantor https://padlet.com/marlonkantor/ex7twcpsld31/wish/205931362 2017-11-11 23:58:49 UTC https://padlet.com/marlonkantor/ex7twcpsld31/wish/205931362
