How to Move in Zero Gravity

Your ability to move in zero gravity depends entirely upon the resources at your disposal. Since there is no gravity to hold you to any particular surface, you have to use whatever surfaces and objects are available to you to propel yourself. Movement in space is best summed up by quoting Newton's Third Law, which states that "To every action there is an equal and opposite reaction." If you exert force upon an object, an equal and opposite force is exerted upon you, and you move.

Things You'll Need

Spacecraft or simulator

Instructions

- 1
  Find something to brace yourself against within your spacecraft. The inner wall of the spacecraft, for example, makes an ideal surface.
- 2
  Push off with hands, feet or another part of your body, propelling yourself in the direction you wish to travel. Your destination should be some object or surface that can absorb the force of your impact without being damaged.
- 3
  Halt your momentum through zero gravity by making contact, via your hands, feet or another part of your body, with the surface you were aiming at. You should either slowly decelerate, or find something to grab on to at your destination, so Newton's third law does not get reapplied, and you go careening off in another direction.
