Rocket Project Refection The aspects I would change from my rocket would be make it lighter because it was fairly heavy for a small rocket so the weight probably made it not fly so high. We could have not used so much glue or sanded down the glue to drop a little weight.
I would change my rocket by making a better nose cone. Our nose cone was like made out of villa folder and it didn’t stay on very well. The first time we launched it, it went pretty high but the nose cone came off to fast and that made the parachute come out to fast which slowed it slowed it down. So we had cut of the top of our rocket and put the parachute in the bottle and nosecone on top and well it didn’t really work, our parachute didn’t come out. Our rockets parachute didn’t really come out of the tube so it was a fail. The first time we launched it as a practice it worked perfectly but it came out to soon. So we had to change the whole top but it didn’t work we could have made the cone heavier so it didn’t come out to fast. Ideas I would use was longer rocket and better parachute. Our parachute was just a plastic grocery bag and we put a hole in it by accident and we used duct tape to fix it. Our rocket was pretty short and if it were to be longer it could have made a higher point we only went up about 38.5 ft. high that is like really sad. The first time it went about 106.3 ft. high that is just a guess though. The exhibition was excellent! The only thing bad was the wind and it was cold. My mom just made it on time to see my rocket but my little brother was to cold and my mom so they left and got me later. But other than the weather it was really fun and exciting, all though our rocket was kind of a disappointment. |
Physics Behind the Rocket Newton’s First Law states that an object at rest will remain at rest and a moving object will remain moving in a straight line at a constant speed, if and only if the net force acting on that object is zero. If this first law didn’t exist our rocket would have gone up, up, up in a straight line at a constant speed. Our rocket on the launch pad was at rest meaning that there was no net force acting upon it. The CO2 was not let out of the bottle so it was just sitting there. The definition of net force is the vector sum of all the forces on an object.
Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated; meaning that when the rocket was launched the CO2 and water made it go up. Also, our rocket had a great amount of mass so that means that the rocket didn’t go high as high as it could have gone if it were smaller. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. That means when one force goes up there has to be another one that goes down. And if one goes left another has to go right. ↔↕. The reason the rocket stayed on the launch pad is because there were equal forces acting upon it. The reason it went up is because the force pushing down in the bottle was released when it was launched. |
