Question

How Does Rocket Accelerate In Space?

Answer 1

Answer:

In space, nothing is changed. If a rocket engine sends a small mass of exhaust flying off at high speed, the large mass of the spacecraft will accelerate in the opposite direction at a much smaller rate. It needs nothing to push against but the inertia of its own fuel.

Explanation:

Rockets and engines in space behave according to Isaac Newton's third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward no air is required. NASA says this principle is easy to observe on Earth.
