Question: how to calculate kinetic energy bbc bitesize?
Answer: Energy can be transferred between stores during motion. ... 
kinetic energy = 0.5 × mass × speed 2
This is when:
Calculate the initial kinetic store of the car in the previous example, if its mass is 1500 kg. ... 
So the value of the kinetic store is 12,000 J or 12 kJ.
