ROCKETS : ROCKETS By Eddie Delacour Newton’s 3rd Law : Newton’s 3rd Law "Forces always occur in pairs. If object A exerts a force F on object B, then object B exerts an equal and opposite force –F on object A" Or As Most People Know It As: : Or As Most People Know It As: "Every action has an equal and opposite reaction" How Rockets Work : How Rockets Work They Need Large amounts of force (Newtons) to make them take off
This Force is usually obtained by by making gases expand very quickly (this is called a propellant).
I first tried using water in a metal bottle heating it to make steam as steam has 10000 times more volume than water. It worked but it was a bit unpredictable.
I then tried using matches wrapped in foil…. Now I Am Going To Do A Very Simple Experiment : Now I Am Going To Do A Very Simple Experiment All I need is two matches, one piece of aluminium foil about 3cm by 8cm and a sewing needle or long pin
How does it work!? : How does it work!? When the tip of the match is heated, it eventually ignites and sends the expanded exhaust gases out through the hole (shown in green). The match rocket has to be mounted on a solid launch pad to make sure all the Newtons that it produces are used in propelling it forward : The match rocket has to be mounted on a solid launch pad to make sure all the Newtons that it produces are used in propelling it forward
