IB Physics SL A.3.7 Mechanical energy conservation
Practise solving speed, height and stored-energy questions by conserving total mechanical energy when losses are negligible.
How this is tested
- apply mgh = 1/2 mv^2 to show a speed from a vertical drop, with clear substitution and units in m s^-1
- include rotational KE when an object rolls without slipping, using I and ω with translational KE in one equation
- find elastic energy from total mechanical energy by subtracting the kinetic part at a stated instant or position
