According to Newton's of motion, the gas escaping from a rocket engine provides the that allows a rocket to fly to space.

According to Newton's third law of motion, the gas escaping from a rocket engine provides the thrust that allows a rocket to fly to space. This law states that for every action, there is an equal and opposite reaction. In the case of a rocket, the action is the gas being forced out of the engine. The reaction is the movement of the rocket in the opposite direction. Here are the steps:

1. The rocket's engine burns fuel and creates hot, high-pressure gases. This is the action.
2. These gases are forced out of the back of the rocket. As they leave, they push against the rocket.
3. According to Newton's third law, the force exerted by the gases on the rocket is matched by an equal and opposite force exerted by the rocket on the gases. This is the reaction.
4. This reaction force, or thrust, propels the rocket forward and, if strong enough, can lift it into space.
