Practise describing energy transfers between kinetic, gravitational, elastic, thermal and chemical stores with CAIE IGCSE Physics questions and mark schemes.
A student drops a heavy ball from a vertical height of 1.8 m above the ground. The ball then falls to the ground. It does not bounce after hitting the ground.
Describe the transfers of energy of the ball between stores from when the ball begins to fall to when it reaches the ground.
gravitational (potential) energy (store before/ as the ball falls)
kinetic energy (store) increases (as the ball falls) OR energy transferred to kinetic energy (store as the ball falls)
(energy transferred from) kinetic energy (store) to internal / thermal energy (store)
