Newton's Third Law says that for every action, there's an equal and opposite reaction. This rule is really important for understanding how rockets launch into space.
When a rocket is about to take off, its engines create a lot of thrust. They do this by pushing gas down very fast. This is where we see the action part:
This upward push is what lifts the rocket off the ground. It’s similar to when you jump off a diving board; you push down on the board, and it pushes you up into the air.
For a rocket to go up, the force made by the engines (thrust) needs to be stronger than the force pulling it down (gravity). We can write this idea simply like this:
Thrust > Weight
Here, weight is how heavy the rocket is because of gravity.
So, to launch successfully, the rocket has to produce enough thrust to beat its own weight. When that happens, the action of the exhaust gases going down helps the rocket rise up. This shows us how Newton's Third Law works in real life!
