Question
Three balls are thrown from the same spot and reach three different maximum heights. Between when it was initially thrown and the moment that each ball is at the position pictured, which lost the most kinetic energy? Ignore any air resistance.
Question 5 options:
Ball A
Ball B
Ball C
No kinetic energy was lost, it was gained.
All three balls lost equal amounts of kinetic energy.
We can't say without knowing the max height each ball reached.

Explanation / Answer
Total energy=KE+PE
as more height give rise to more PE(as PE=mgh)
As total energy should be conserved,therefore gain in PE means loss in KE
Therefore, Ball C have greater loss in KE
