Newtons+3rd+Law

= Newton's 3rd Law - Law of Action-Reaction = =Every action has an equal and opposite reaction= toc =So What Does This Law Mean?= Everything you do, there is always some sort of effect. If I push a ball the reaction is the ball moving/traveling away. If two people push on each other (like in the picture above) they will both go in the opposite direction. The two people have to be the same weight because otherwise the effect they would have would be different.

=**__WATER ROCKET__**= media type="file" key="cutrocket.mov" width="300" height="300" The small video clip above shows the proof of the 3rd Law. The air has a reaction with the water which causes the bottle to expand and the water to come flying out. The way this happens is because the air doesn't like having to be so compressed so it pushes down on the water, which causes the water to come shooting out the bottom. Then what happens after that is, the bottle goes up. The same idea occurs with the balloon, air comes out the bottom of the balloon and shoots in the opposite direction of which the air is coming out.

The way we did this experiment was Ellen, Bryce and Mr.Bentley pumped air into the bottle using a pump. While as I, Elise stood there pulling a leaver while holding the bottle straight up, the leaver was slowly letting in more and more air. As the air went it the air became compressed and then the air couldn't hold up with all the pressure and let go. In the end I became very wet and cold.

If we were to do this experiment differently I would chose to have a rain jacket, and find some other way to make it a bit quicker. Before we put on the movie Ellen and Bryce both tried to pump air into the bottle but did not succeed. Then Mr.B tried/fixed it and it started to work. (SLOWLY)
