Question

when is workdone = to gravitational energy

workdone= to kinetic energy

work done = to thermal energy

Answer 1

2)  work  done  =  kinetic energy (  when  a car  moves)

3)   wrk  done   =  thermal  energy  (  when   an  electric  oven  cooks)  

Answer 2

Work is just the change in energy in that form

Gravitation change is if you move masses closer together or further apart.

Kinetic change would be accelerating something

Thermal change is a little tougher, it involves pressure and volume
