What are ejection velocities?

Ejection velocities are how fast things get pushed out from somewhere else, like when you squeeze a toy that shoots little balls.

Imagine you have a balloon filled with air. When you let it go, the air rushes out really quickly, and the balloon zooms around in all directions. That’s kind of what happens with ejection velocities, instead of air and balloons, we might be talking about spaceships or even tiny particles!

Think of a water gun. When you press the trigger, water is pushed out through the nozzle. The harder you push, the faster the water comes out, that’s like having a higher ejection velocity.

In space, when something like a rocket pushes gas out really fast, it gets pushed forward in return, just like how you might be pushed back when you squeeze that toy or shoot a water gun!

So ejection velocities are about speed and push, the faster things go flying out, the more of a kick they give to whatever is pushing them! Ejection velocities are how fast things get pushed out from somewhere else, like when you squeeze a toy that shoots little balls.
