 * Formulae**

Here are all the formulae we have learned so far...You are welcome to add anything new!

Measuring gravitational potential energy of an object depends on the vertical height above the ground(//h//) in **metres**, it's mass(//m//) in **kilograms**, and the pull of gravity on the mass(//g//) in **metres per second squared.** or Ep= Weight X height**
 * __**Potential Energy**__
 * Ep=mass X gravity X height

The formula for kinetic energy is given by the equation: where Ek is the kinetic energy of the object (**in joules**), //m// is the mass of the object (**in kilograms**) and //v// is the speed of the object (**in metres per second**)
 * __**Kinetic Energy**__
 * Ek=1/2 X m X v squared**


 * **__Distance,Speed and Time__**
 * Average Speed=Total Distance travelled/Total time taken**

Speed=metres per second Distance=metres Time=Seconds S=D/T

Acceleration is the rate of change of velocity.
 * __**Acceleration, speed and time**__


 * Acceleration=Change in velocity/Change in Time**


 * __**Force, Mass and acceleration**__

Force=Mass X Acceleration
 * //F=m x a//**


 * __**Work**__

Work=Force x Distance
 * //W=FxD//**


 * __**Power**__

Power is measured in Joules (J) or Watts(W)
 * Power= Work done/Time taken**
