For the 10th-grade physics and math rocketry unit, we were tasked with building a prototype so that we knew the basic functions, workings, and goals we wanted to tackle with our rocket.
A goal for me personally was to fully understand the physics behind a rocket in flight, I feel that I have tackled my goal fairly well, now not only am I interested in learning more about rocketry in general, but I feel If I was given the opportunity I could make a more successful rocket overall, in terms of speed, height, weight and velocity.
The engineering/ design process plays a big role in this project in order to maximize the efficiency of our rocket builds.
Define, Ask, Imagine, Plan, Prototype, Test, And Improve.
These are the steps we take when designing and engineering any kind of build
Once there is no more pressure in the chamber, you can describe a rocket in flight using the equation
h(t) = -16 t 2 + 128 t + 320, which describes the flight of a rocket once the pressure is empty. We use quadratics to describe a rocket in flight so that every single detail is documented, and in the case that there are actual living people on board everything is taken into account for maximum safety. We fire a rocket in a certain position and angle depending on whether or not you are trying to leave the atmosphere, velocity is simply how we describe the speed of an object moving in a certain direction.
Acceleration on a graph would start at zero and depending on the speed of the object the line would be steeper. For example, if theres a rocket accelerating at approximately 120 meters per second the graph line would be at a very steep angle.
A quadratic is an equation where the highest degree of any variable is 2. Quadratics relate to projectile motion because in simple cases its height from the ground at any give time using the equation
h=at2+bt+c height = a t 2 + b t + c.
G force is simply a way to describe acceleration and its affect on objects. 1 g is the force we feel going at a speed of 0, it the force gravity on us, and the faster your going the harder that force will press down on you. Free fall is gravity acting on a force with the absence of normal force from below, causing the object to free fall.
Inertia or an object in motion stays in motion, unless acted on by an unbalanced force. If your in your car going 60 miles per hour and decelerate to 0 miles per hour in 1 second, the force on your body from such a rapid deceleration could do irreparable damage. But if your driving at 60 mph and decelerate to about 40 mph over the coarse of 20 seconds your body will be slowed as the car slows and not keep traveling at the original speed. The net force acting on you is the combination of all forces evened out, so the gravity pushing on you is equal to your body weight and the ground pushes back, giving the equal amount of force.
Newtons second law: force and mass. Force is everything you feel acting on you all the time except inertia. For example: Normal force the force of the ground you’re standing on, or the wall your leaning against, it is anything that gravity is pushing you against, and it pushes back giving the required force to hold you. Friction is two apposing forces colliding, For example: when you walk the force of the shoes on the ground pushing against each other, propel you forward. Drag is where there are 2 forces creating friction and physical drag on one force experiencing no friction. For example: A parachute slowing a rockets fall. Weight is how much an object is pressing down on a normal force, where mass is a measurement of how much matter an object contains.
Newton's third law. If object A puts a force on object B, object B will put an equal amount of force on object A. This is how every rocket lifts off by putting out a curtain weight of thrust onto the ground or normal force and lifts the rocket off the ground.
