Vehicles on Earth move thanks to the resistance of the air, but in space There is no air or any atmosphere.

However, rockets in space It can move at high speeds. Let us explain this question, which forms the basis of modern space exploration, using Newton’s famous law of motion.

What does Newton’s third law of motion say?

Newton’s laws of motion are three laws that reveal the relationships between the forces acting on an object and the motion of the object. ‘Action-reaction’ law The summary of the third law, called:

“For every action there is an equal and opposite reaction.”

To explain further; When a force acts on an object, it moves away from the object towards the force. a reaction force of equal magnitude and opposite direction comes forward. The important thing is that these forces are in the same direction.

So how does this law explain the motion of rockets in space?

When the rocket engines start, the fuel burns and gas is quickly released. When this gas leaves the back of the rocket, a thrust is created in the opposite direction of the gas. The rocket thus forward is being pushed.

In other words, the rocket doesn’t need air or atmosphere, or any friction against the rocket’s thrust, to go. Created by the gases coming out of the back of the rocket, the rocket’s own propellant and the response is sufficient.

In the world, things are not the same.

Yes, rockets can move through space, which we explain with Newton’s third law. with its own driving force It is possible, but the same is not the case with jet engines on our planet.

Vehicles on Earth move by needing air because of rocket engines oxidizing agent required for combustion they carry with them.

Jet engines, on the other hand, enter the atmosphere to carry out the combustion process. to oxygen in the air it needs. Therefore, they can only move through the Earth’s atmosphere.
