If :
The total energy of a falling rock = G.P.E. (mass x gravity x height) + K.E. (0.5 x mass velocity^2)
But if a rock reaches terminal velocity (i.e velocity remains the same) but height keep decreasing, then surely Kinetic energy is remaining constant and Gravitational potential energy is decreasing. Where is the loss of energy going?
Has the first law of thermo dynamics been broken? or is it simply converted into sound energy and heat energy due to air resistance? HHmmmmmm
