nuclear propulsion - the use of a nuclear reactor either to produce electricity to power an engine (as in a nuclear submarine) or to directly heat a propellant (as in nuclear rockets)

roll - the act of rolling something (as the ball in bowling)

throw - the act of throwing (propelling something through the air with a rapid movement of the arm and wrist); "the catcher made a good throw to second base"

push, pushing - the act of applying force in order to move something away; "he gave the door a hard push"; "the pushing is good exercise"
