A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. Newton’s laws can be used to explain this his laws in the simplest terms can be explained like this:
First law- Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force.
Second law- Force is equal to mass times acceleration.
Third law- For every action there is always an opposite and equal reaction.
For the rocket to launch it needed to be propelled by something, for our rockets we used regular air and compressed it. Upon releasing the stopper Newton’s first law went into effect which states that for something to move a force must act upon it in this case the gas moving out of the bottle. When the stopper was pulled the pressure in the bottle forced its way down, which applied the force to start the motion of the bottle. His 3rd law can also explain this because the water going down forces the rocket in the exact opposite direction the water goes. Which is why one time when we shot the rocket it flew at an angle. Also it shows why the launchers had stoppers, because if they didn’t the cork wasn’t strong enough to hold that pressure and would cause the rocket to begin flight prematurely. His second law can be used to describe how high and fast the rocket will go. If you wanted it to go really high and fast you would just pump more pressure into it then if you didn’t want it to go that high. You can determine how much force is needed by multiplying the mass by the acceleration.
Our rocket was fairly decent the only problems were that the wings were not completely stable. Our egg survived in the capsule we built and one other egg even survived with out being in a capsule at all.
Dropper Poppers are rubber toys that resemble half a rubber ball and are shaped as hemispheres. They are turned upside-down (or inside-out), left on a flat surface, and after approximately 5 seconds, the dropper popper flies upwards, going higher than its original position. Simply put, the rubber needs to return to its original position, and creates a high surface tension. The rubber’s urge to return to its original position also causes instability within the structure of the dropper popper. When you drop the toy onto a flat surface, the inverted part pops back out, slams into the surface, and causes the toy to bounce into the air. This is a very basic explanation of what causes the dropper popper to act the way it does, and the physics principles
With respect to the rocket program, the A1 rocket was first completed at the end of 1933. It was only 5 feet long and powered by an alcohol and liquid oxygen motor. Gener...
Law 1. An object continues in its initial state of rest or motion with uniform velocity unless it is acted on by an unbalanced, or net external, force.
Newtons second law can be indentified more easily using the equation F=ma. This is an equation that is very familiar to those of us that wish to do well in any physics class! This equation tells us many things. First it tells us the net force that is being exerted on an object, but it also tells us the acceleration of that object as well as its mass. The force on an object is measured in Newtons (I wonder where they got that from). One Newton is equal to one (kg)(m)/s^2. For example, if superman pushes on a 10,000kg truck and it is moving at a rate of 2m/s^2, then the force that superman is exerting on the truck is 20,000N. For those of us that wish to move on in the field of physics, Newtons second law (F=ma) will forever haunt us!
In 1687, Newton published Philosophiae Naturalis Principia Mathematica (also known as Principia). The Principia was the “climax of Newton's professional life” (“Sir Isaac Newton”, 370). This book contains not only information on gravity, but Newton’s Three Laws of Motion. The First Law states that an object in constant motion will remain in motion unless an outside force is applied. The Second Law states that an object accelerates when a force is applied to a mass and greater force is needed to accelerate an object with a larger mass. The Third Law states that for every action there is an opposite and equal reaction. These laws were fundamental in explaining the elliptical orbits of planets, moons, and comets. They were also used to calculate
Newton's Laws can be found in the textbook, Physics for Scientists and Engineers by Serway.
The major problem with these rockets is fuel. It needs huge amount fuel , bigger that what earth could produce. For example, Nu clear fusion rockets would need about “1000 supertankers full of fuel”
In this paper you will learn so much about rockets you can become a rocket specialist. Many may ask how do rockets work? Many will respond that they are pushed against something but that is wrong. Since rocket's main purpose are to travel in space where there is nothing, not even air they can not rely on “something” to push themselves against in space. This is the right answer to how rockets work; Rockets use fuel, they burn the fuel and it turns into hot gas.
Many of the the most important features of modern rockets, missiles, and even spacecraft use the principles pioneered by Dr. Robert Goddard. Before his work, many people didn't even believe thrust could propel a rocket in a vacuum and, because of this, he was ridiculed by the New York Times when he proposed that space travel with rockets was possible4. When he tried to tell the U.S. Army about the possibility of the Germans using rockets as weapons just before World War II, he was rebuffed. What he had warned became a reality however, when German V-2 rockets hit London. After the war was over, German scientists admitted that much of the design for the V-2 had been taken from Goddard's patents, which were publicly available4.
This law ties in with the balloon racer lab because this equation was used when trying to calculate the force and acceleration of the racer. After doing the calculations, we found that our fastest trial was in trial 3 when the racer went 0.82 m/s2 and our slowest trial was in trial 2 when the racer went 0.58 m/s2. Mass and force affected both of these results because in trial 2, we had lots of tape on the racer and condensation inside the balloon which raised the mass of the racer and caused our acceleration to be lower. After taking lots of tape off before trial 3, we noticed a huge jump in acceleration from trial 2 because now that the mass of the racer was lower. Therefore, the racer traveled at a higher acceleration in the trials after lowering the
The UAF Student Rocket Project builds and flies sounding rockets with help from Wollops Flight Facilty.
According to mechanical physics, a force is an effect that may cause a body to accelerate. Also as stated in Isaac Newton’s second law of motion, force is a vector quantity (has magnitude and direction) that is proportional to the product of the mass of a body and its acceleration.
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely proportional to its mass. (F=ma)(Newman)
The first law is, “every object in a state uniform motion tends to remain in that state of motion unless an external force is applied to it.” This means if an object at rest tends to stay at rest, then an object that is moving tends to stay moving. So when a force is applied to the rested object, it should start moving, if the force is great enough. This is commonly referred to the, “law of inertia.”
Projectile motion is the force that acts upon an object that is released or thrown into the air. Once the object is in the air, the object has two significant forces acting upon it at the time of release. These forces are also known as horizontal and vertical forces. These forces determine the flight path and are affected by gravity, air resistance, angle of release, speed of release, height of release and spin
