Terminal velocity is the constant speed (in a particular direction) a body reaches when the forces are balanced, i.e. acceleration = 0 m s^-2.

An example of...

In fossil fuels powered power stations fossil fuels (such as coal) are burnt to generate heat. This heats is used to heat a large amount of water and turn it into steam. The movement of the steam cause...

The definition of acceleration is the rate of which an object's velocity changes.

Acceleration = Change in Velocity ÷ Time

Therefore, constant acceleration ...

Firstly, write down the information you know. 

S (displacement) - unknown 

U (inital speed) - 10m/s

V (final speed) - 50m/s

A (acceleration) - we...
