Question

which of these is correct?
velocity of coconut p.e of coconut
1-decreasing decreasing
2-increasing decreasing
3-increasing increasing
4-decreasing increasing

Answer 1

Hi sweetie,

As a coconut is falling down, the only force acting on it is the gravitational force (its weight) if you neglect air resistance. So as it is accelerating as it falls, velocity ______.

P.E. of coconut = mgh, where m = mass of coconut, and h = height of coconut above ground.
So as the coconut falls, its height above ground (h) decreases, so P.E. _______.

Do fill in the blanks above! (:
