You've probably seen a balloon go whizzing around in the air before, but why does this happen? You might say that it's because the air from the balloon pushes it along––and you wouldn't be wrong! But why don't we go whizzing around the room when we, say, blow out of our mouths?
The answer can be found by investigating thrust, a force that occurs when an object (i.e. a Space Shuttle, balloon, or person) expels or accelerates mass in a specific direction. This might sound complicated at first, but we can get the hang of it by thinking about our balloon example:
In this experiment, we're going to take a closer look at thrust and forces and see what happens when we use our knowledge of thrust to our advantage.
Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
