A
kinetic energy=0.5 x mass x (speed)2
2
Q
give the equation that links gravitational potential energy , mass , gravitational field strength and height
A
gravitational potential energy= mass x gravitational field strength x height
3
Q
give the equation that links power, energy transferred and time
A
power = energy transferred / time
4
Q
give the equation that links work done, time and power
A
power = work done / time
