Speed, Force, and Acceleration Caculations

First one: 

Speed:

the rate at which someone or something is able to move or operate

-------------------------------------------------------------------------

How to calculate Speed:

For a body moving at a uniform velocity you can calculate the speed by dividing the distance traveled by the amount of time it took, for example one mile in 1/2 hour would give you 2 miles per hour. If the velocity is non-uniform all you can say is what the average speed is. Same calculation.

Force:

strength or energy as an attribute of physical action or movement

---------------------------------------------------------------------

How to calculate Force:

The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration. 

Acceleration:

increase in the rate or speed of something.

---------------------------------------------------------------------------------------

How to calculate Acceleration:

Given initial velocity, acceleration and time calculate the velocity. Given velocity, acceleration and time calculate the initial velocity. Given velocity, initial velocity and time calculate the acceleration. Given velocity, initial velocity and acceleration calculate the time.

The reason I gave the definition is because you should know the word, just in case you didn't know it. Remember to write down both the definition and the way to calculate each and every one of them. The process should explain the easier way to do each of them. Again, remember, write down the way to do it as well.
