ocr: How does a rocket convert energy? Arocket's fuel must contain all the energy the rocket will need to complete its journey. CHEMICAL ENERGY TSE - - KINETIC ENERGYT HEAT ENERGY Energy changes during lifroff The rocket's fuel is a store of chemical energy. As the fuel burns, this energy changes into another form heat energy - in the exhaust gases. The hot gases expand rapidly and escape through the exhaust nozzle at high speed (in other words, with a lot ofkinetic energy). The rocket reacts to the backward movement of the gases by moving forward, gaining kinetic energy itself. All the kinetic ene ...
