Like jet airplanes, space rockets work on a principle called action and reaction (another name for Newton's third law of motion). The massive force (action) generated by hot gases firing backward from a rocket's engines produces an equal force (reaction) that pushes the rocket forward through space.
Answers. Best Answer: You're moving forward. So your velocity is forward. Since your inertia when you're moving is present in the direction of movement, you will continue moving forward. Inertia keeps you in the 'current' state of motion, be it moving or unmoving.he bicycle, when upright, is pulled down equally on both sides by gravity. The right side is just as heavy as the left side, so the bicycle stays upright. Although, yes you might argue, when you try and balance it when it's not moving, it won't stay up!
