To end this quarter we ended off with a bottle rocket project. This project lead us to become more educated with Newton’s laws of motion. The bottle rockets also lead you to learn about mass, force, and acceleration. As you know the first law of motion is that if objects at rest will stay at rest, or objects in motion will stay in motion, unless acted upon by an unbalanced force. Well in order for the rocket to lift off it will need force applied to it. It is required to add water for your rocket and you don’t want to add too much because then the rocket will be too heavy. As you told us in class the best thing to do is add a little at a time and test it. You want your rocket to be stable. The height and weight do matter but test as much as possible to be sure it will work.
The second law of motion is the acceleration of an object is directly related to the force applied on the object and oppositely related to the mass of the object. So this is based on the speed of the rocket. And the speed is also involved in what the weight of the rocket is and the force it has from the water. Because the mass and acceleration is being forced going up. The rocket needs enough force in order for it to take off. You can’t have a huge mass and not enough force, because it will not work.
And the third law of motion is, for every action there is always an opposite and equal reaction. So then when you have your rocket on the launch pad and all ready then its determining on the motion of the rocket being equal to and opposite from the nozzle. Like if the rocket goes one way and the water goes the other way. You want it to be centered and balanced. Figuring on how many times you have tested it will and can improve on your final launches. And then you will have a bigger idea on how the water being forced down is going to equal the force when the bottle goes up.
