Question: How do rockets manoeuvre in space without any friction for thrusters to push against?
friction, rocket, space, thruster
Asked by ROYLE to Norah, James, Dominic on 15 Mar 2017.

Because of Newton’s law: Every action has an equal and opposite reaction. So you expend fuel out of a nozzle in one direction, and the spacecraft goes in the other.
Plus, friction wouldn’t really be relevant anyway, except that it would slow the rocket down if it was running along the ground for example.
