Maths for P2

speed in metres per second (m/s) = \(\frac{distance  travelled  in  metres  (m)}{time  taken  in  seconds  (s)}\)acceleration = \(\frac{change  in  velocity}{time  taken}\)a = \(\frac{v-u}{t}\)Where:a = acceleration in metres per second squared (\(m/s^2\))v = the final velocity in metres per second (m/s)u = the intial velocity in metres per second (m/s)t = the time takes for the change in velocity in seconds (s)

gravitational potential energy = mass x gravitational field strength x height\[E_p=mgh\]Where:\(E_p\) = gravitational potential energy in joules (J)m = mass in kilograms (kg)g = gravitational field strength in newtons per kilogam (N/kg)h = height in metres (m)

kinetic energy = \(\frac{1}{2}\) x mass x \(speed^2\)\[E_k=\frac{1}{2}mv^2\]Where:\(E_k\) = kinetic energy in joules (J)m = mass in kilograms (kg)v = speed in metres per second (m/s)
