Abstract kinetic energy recovery system (kers) is a system for recovering the moving vehicle's kinetic energy under braking and also to convert the usual loss in kinetic energy into gain in kinetic energywhen riding a bicycle, a great amount of kinetic energy is lost while braking, making start up fairly strenuous. Thrust is the force which moves any aircraft through the air thrust is generated by the propulsion system of the aircraft different propulsion systems develop thrust in different ways, but all thrust is generated through some application of newton's third law of motion for every action there is an equal and opposite reaction.
