|
energy
|
The capacity to perform work
|
|
|
power
|
The amount of energy available or used over a given period of time. Eg. Joules per second.
|
|
|
work
|
Is the amount of energy transferred by a force acting through a distance.
|
|
|
joule
|
A basic unit of energy, a very small amount of energy. Eg. 17.2 megajoules= 12 200 000 joules.
|
|
|
watt
|
The unit for power. Power (watts)= energy (joules) / time (seconds). One watt= one joule per second.
|
|
|
potential energy
|
the energy stored by an object due to its position
|
|
|
kinetic energy
|
energy of motion
|
|
|
mechanical energy
|
ehergy required by an object which work is done can be in the form of kinectic or potential energy
|
|
|
electromagnetic/light/radiant energy
|
Flows from one place to another in the form of rays. Eg. Ultra violet, X-ray, Radio waves & heat. (CE)
electromagnetic/light/radiant energy- energy of electromagnetic waves(light) it is both visible and in visible depending upon this wave length |
|
|
chemical energy
|
a form of potential energy stored in the bonds in chemicals it is released when the bonds are broken
|
|
|
electrical energy
|
Such as that of lightning, a battery or appliance resulting from the existence of charged particles creating a current.
|
|
|
nuclear energy
|
The energy between the strong bonds within the nucleus of atoms, released through fusion or fission.
|
|
|
thermal energy
|
The energy of heat from one substance to a cooler one.
|
|
|
temperature
|
Is a measure of the average kinetic energy of the molecules within a material.
|
|
|
heat
|
Plays an important role in nearly all energy transformations. The molecules of all objects are in motion, that is they have kinetic energy.
|
|
|
transmission
|
Act of transmitting; transference; a passing through any body, as of light through a glass.
