energy transfers: bungee jumper Flashcards
what happens at the start of the jump?
all of the energy in the system is the store of gravitational potential energy
what happens when the jumper falls?
energy is transferred from the gpe store to the kinetic energy store
what happens when the bungee rope just starts to tighten?
the kinetic energy store is now at its maximum
what happens when the rope is fully extended?
the kinetic energy store is zero, because the jumper is not moving
what happens when the rope recoils?
the energy is transferred from the elastic potential energy store back to the kinetic energy store
why does the bungee jumper never return back to the original position?
because the energy is dissipated as thermal energy, due to friction with air particles and stretching affects in the not fully elastic rope
