Density= How heavy something is for its size(does change) Density= mass divided by volume Units=g/cmCUBED |
Density= Mass divided by Volume Volume = Length times width times height Mass= density divided by volume I need to know how many cm cubed are equal to 1g of mass. |

Kinitec energy Formula = half * mass * speed squared |
Energy in gases Formula= Heat energy transfered = mass of water * 4.2 change in temperature. It takes 4.2 joules to heat 1g of water by 1°c.

Renewable= Pros: not polluting the world keeping our world tidy. |
Non-Renewable= Cons=Polluting the world wasting natural resources. |

Gravitational to kinitec= Gravitational to kinitec anything raised has gravitational potential energy without another force being used.If it was dropped it would have kinitec energy. G= strength of gravity gravitaional potential energy depends on the object's mass,the gravitational field strength(on earth is 10 newtons 1kg) and the change of height. |
Efficiency Formula Efficiency generally refers to how far we are getting the particular outcome for the given input with as much less wastage as possible. Efficiency formula = n=useful powerout divided by total energy in * 100% |

Soluble: can be dissolved,so we can no longer see the solid. Insoluble: Cannot be dissolved,solid remains visible in liquids. Solvent:Liquid used to disolve into solid. Solution:Mixture of solvent with solute dissolved in it. Independant variable:The one you are changing in the first column of the table and goes on the bottom x axis. Dependant variable:The results you are measuring.Goes on the vertical y axis. Bar graph:to display categoric variables,like hair colour name ,type of animal. |
