- Rockets work by expelling hot exhaust that acts in the same way as the basketball. The exhaust's gas molecules don't weigh much individually, but they exit the rocket's nozzle very fast, giving them a lot of momentum. As a result, the rocket moves in the opposite direction of the exhaust with the same total oomph.

Rockets are a perfect example for learning about forces and Newton’s laws of motion. During lift-off, there are two forces acting on a rocket: thrust pushes it forwards by expelling gases in the opposite direction, and gravity pulls it downwards. Once a rocket is moving, drag acts on the rocket in the opposite direction to its motion. The rocket wi...
The pressure inside the International Space Station (ISS) is similar to the pressure on Earth, which is 1 atm. Outside the ISS, however, the pressure is about 10-12 atm. If an astronaut were to travel outside the ISS without a space suit, any moisture – such as the saliva on their tongue or the water in their eyes – would begin to boil. This is bec...
Galileo famously concluded that all objects fall at the same speed, regardless of their mass. We now know that, while this is true if there is no air resistance, this isn’t usually the case on Earth. In the hammer-feather drop experiment performed on the Moon during the Apollo 15 mission, astronaut David Scott held out a hammer and feather and drop...
