Newton's Third Law tells us something cool: for every action, there's an equal and opposite reaction. This idea is really important for how rockets work.
Let’s break it down:
Exhaust Gases: When a rocket pushes gas out really fast from the bottom (that’s the action), it pushes itself up into the air (that’s the reaction!).
Thrust Calculation: The strength (or thrust) of the rocket can be figured out with this simple idea:
Thrust = mass flow rate of gas × speed of the gas
Here, the mass flow rate is how much gas is used each second, and the speed is how fast the gas is moving as it comes out.
Practical Implications: Today’s rockets are super powerful. They can produce thousands of units of thrust! This power helps them fight against Earth’s gravity, which pulls everything down with a force around 9.81 meters per second squared.
Thanks to these principles, rockets can take off, steer, and work well in space.
