INTRO:
This semester in Math 10 we were learning about how to create a high-flying water rocket that has some sort of parachute before it lands. In math we learned about quadratic equations, representing velocity using vectors. Quadratic equations are equations where the largest exponent above a variable is 2. In physics, we focused on Newton's 3 laws of motion. While making these rockets we used the engineering design process. The engineering design process is made up of 7 steps. First you ask a question or find a problem. We did this when starting the process and asking how we can build a rocket out of a bottle and create a parachute deployment system that works. Next you research. Which means finding the cause of the problem and the details. After you know details about the problem you can start to imagine how to solve the problem. When researching we looked at what other people did and how they built their rocket. Next you will be planning out an idea to solve your problem. We used this when drawing our blueprint and deciding what each aspect was going to look like. Next you need to create a prototype. This is when we started building our rocket. In this step you are using all of the research and knowledge from the other steps. Then you Test. In this step you are evaluating the prototyping to see what you can change and what works. After testing you will improve your prototype and fix the things that didn't work while testing, to create your final prototype. We did this by changing things about our rocket that didn't work the first time.

MATH:
This September in math we learned about quadratic equations, representing velocity using vectors. Quadratic equations are equations where the largest exponent above a variable is 2. We can use these quadratic equations to help figuring out different aspects of our rocket including initial velocity, time, and height. We can define a quadratic function as y+x2. The position represented on the height vs time graph can be represented by a point where the rocket's height is given time. The velocity on the graph can be represented because the slope is the velocity. The acceleration is represented because acceleration is the curve itself and represents a change slope or changing velocity. A quadratic function can be represented as h(t) = , g represents the acceleration from gravity, and represents the initial velocity, and it represents the object's initial height. Velocity is the direction of the movement of an object. While acceleration is the rate of change of velocity. G represents gravity.

PHYSICS:
This semester in physics we focused on Newton's 3 laws of motion. Newton's first law is “An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.” This law includes inertia, net force and normal force. Inertia is the property of matter by which it continues in its existing state of motion unless it is changed by an external force. The net force results in a change in motion. The force that creates all of the pushing and pulling forces that are actually applied to an item is known as the net force. Which results in an object that will accelerate in the direction of the net force if the forces pushing and tugging on it are out of balance, or if there is a net force acting.
But the equilibrium is when forces are balanced and the object does not change its motion. Normal force is the force that surfaces exert to prevent solid objects from passing through each other. This is important regarding the first law because the rocket stays sitting on the launch pad and until you pull the string is stays in its state of rest. Objects an rest on earth with a constant force of gravity because whatever the object is rest on is exerting a force on the object.
Newton's 2nd law is “the force on an object is equal to its mass times its acceleration.” (a=F/m) The force on an object is the push or pull with mass and it causes it to change its velocity. One way to measure force is with newtons. A newton is a force that can be used to accelerate one kilogram of mass one meter per second squared. Friction, drag, and weight are all types of force. Friction resists motion when it comes in contact with another surface. Drag is when an object interacts and has contact with a solid body with a fluid. While weight is the measurement of the heaviness of an object and the force of gravity on an object. Although mass is not a force it is used in the equation (a=F/m). Mass is a measure of inertia the greater the mass of an object, the smaller the change produced by an applied force.
Newton's 3rd law is “when two objects interact, they apply forces to each other of equal magnitude and opposite direction.” Some examples are when you are swimming you are pushing against the water you are being pushed forward by the water. Aswell as a book resting on a table the weight of the book is acting in the downward direction on the table and the table is exerting an equal force upward. These are both examples where objects are exerting force on each other. This is know as a system.

Discussion and Analysis:
PRE- LAUNCHAt this stage of our rocket’s launch the forces being applies are Normal Force and gravity. Even if the object isnt moving gravity wille always be acting apon the object. These force cancel each other out and creating anetforce of zero. This results in the rocket not changing position or motion. This connects to the first law because the rocket is not moving, even thought there are forces acting apon it the forces acting are at a net force of zero. |
LAUNCHTake off is the second stage of a rocket's flight path. During launch the rocket will be experiencing thrust and gravity. The force of thrust is going upward even though the water is being pushed out the end. Going down is gravity. During launch there is a lot more thrust then there is gravity. This an example of the 3rd law because the water is being pushed out of the rocket which pushes the rocket in the opposite direction.
|
RISING FLIGHTRising Flight this is the third part of the rocket's flight path. During this segment of the rocket's flight path it will be experiencing only one force. Because all the water is out of the bottle there is no thrust being applied to the rocket. Even though it is still heading upward it does not have a force pushing it up. So the only force being applied is gravity on the bottom of the rocket. Rising flight is the first law being it is coniutines to go up until a force is asting apon it. This being gravity.
|
CONTROLLED DESCENTThe last stage of the rocket's path is Controlled descent. Now that the rocket is slowly moving back to the ground it gained a force. Now that the rocket is moving down it is experiencing gravity and drag on itself.The rocket is experiencing drag because of the parachute and the backslider method. The more surface area the rocket has and the faster the rocket is going effects weather the drag. This demonstrates the second law because the net force is zero resulting in the rocket neither speeding up or slowing down.

REFLECTION
Leadership and Teamwork:
During this project me and my partners worked well together. Each day we showed up to get our rocket done. During this project we didn't have any conflicts. We didn't have any conflicts because we all were doing work and never were not doing anything to help. When working with this group we all communicated if we needed help or wanted anything to change. I was a leader in this group because If a group member wasn't doing anything to help I would encourage them to do so. I was also a leader by taking initiative and making our blueprint. I was a follower when others had ideas and if they asked me to do something. For example when I helped Alex attach the nose fin, and we both made the parachute. During this project each person has their strengths and weaknesses. With that we assigned the people things they would be good at, and did not give them something they couldn't do. For example throughout the project I let Aiden help me with attaching the fins and little things.
