How does a rocket work with refrence to Newton's laws of motion?

Answer 1

It works quite well. Here's how.

1. The rocket won't move until the engines are fired. That's the law of inertia. It's at rest, and it remains at rest until it's acted upon by an outside force. The opposite is true, too. If a body is in motion, it wants to remain in motion unless it's acted on by an outside force.

2. When the rocket motors are fired, the rocket takes off. It accelerates, and that's the law of acceleration. Force = mass x acceleration. The more mass it has for a given thrust, the less acceleration it has. The more thrust it has for a given mass, the more it accelerates.

3. The rocket motors inject hydrogen and oxygen (typical NASA "big rocket" fuel) into the throat of the motor where it burns quickly and hotly. Superheated combusted gas is rushing out the exhaust nozzle with tremendous force, and an opposite force is generated. That opposite force causes the rocket to be accelerated up (since the nozzles are pointed down). For each reaction there is an equal and opposite reaction, Newton's third law.
