  • Let us imagine an apple of mass ‘m’ falls from a height h. 
  • Before starting to fall down, its velocity is zero. Hence its energy is purely potential. 
  • When it falls down, its gravitational potential energy gradually converts into kinetic energy, but the entire energy in the system remains same. 
  • When it strikes the ground, its energy is fully kinetic, till its velocity becomes zero.
