Answer 1

Answer:

Law of Conservation of Energy Derivation. ... Consider a point A, which is at some height 'H' from the ground on the tree, the velocity of the fruit is zero hence potential energy is maximum there. E = mgH ———- (1) When the fruit is falling, its potential energy is decreasing and kinetic energy is increasing.

escape velocity is defined as the minimum initial velocity that will take a body away above the surface of a planet when it's projected vertically upwards

k. e= 1/2 mv^2 IS THE FORMULAE FOR ESCAPE VELOCITY
