Conservation of Momentum
Purpose: To show that momentum is conserved in a closed system by illustrating the conservation of momentum in an elastic collision and an inelastic collision.
Method: If momentum is conserved in a closed system, the total momentum of the system before collision should equal the total momentum of the system after the collision. Strobe photos will be used in the calculations that will prove that momentum is conserved.
1.) Elastic collision: A strobe photo will be used that shows a large glider smashing into a smaller glider which is initially at rest. This will cause the smaller glider to move and the large glider will continue to move also.
2.) Inelastic collision: A strobe photo will be used that shows a glider smashing into another glider which is initially at rest. When they collide the two gliders will stick together and will move.
-The masses, distances and times will be measured in order to calculate the momentums of the systems before and after collision occurs.

The experiment done in the lab supports the law of Conservation of Mass because we used the reactants and simply rearranged them to create the products without adding or removing anything. For the experiment we used candy and marshmallows. The green candy symbolized carbon atoms, the red ones hydrogen atoms, and the marshmallows represented oxygen atoms; we also used toothpicks which illustrated bonds keeping them all together. The chemical reaction for photosynthesis is the product of six carbon dioxide plus six water atoms is glucose (sugar) plus oxygen. We started by making the food into the reactants, the ingredients for the chemical reaction; six green candy drops and twelve marshmallows plus twelve red candy drops and six marshmallows.

The Gravimetric Stoichiometry lab was a two-week lab in which we tested one of the fundamental laws of chemistry; the Law of Conservation of Mass. The law states that in chemical reactions, when you start with a set amount of reactant, the product should theoretically have the same mass. This can be hard sometimes because in certain reactions, gases are released and it’s hard to measure the mass of a gas. Some common gases released in chemical reactions include hydrogen, carbon dioxide, oxygen and water vapor.
Once a paintball gets into the air its flight is much like that of a golf ball. There are a verity of forces that act upon the ball once its in the air. The ball always has the force of gravity acting on it. This causes the paintball to travel in an arc and return to the earth.
Different collisions took place throughout the process of the Rube Goldberg Machine. This included Elastic and Inelastic collisions. An example of an Elastic Collision in our Rube Goldberg Machine is when the car went down the track and collided with another car. Elastic collisions are defined as collisions with conservation or no loss of momentum. This is proven by the first car which transferred its momentum to the second car thus momentum was perfectly conserved. An Inelastic Collision is seen in our project ...

An elastic collision between two objects is one in which total kinetic energy (as well as total momentum) is the same before and after the collision.

Together, they are attached to one end then to a counterweight on the other. This arm is then hooked up with a tripod or any supporting device. This is like a seesaw when you see it, with the fulcrum located at the counterweight’s closer end. This gives the camera a wider range of motion.
The mangonel catapult was the most well known one. The way this catapult functioned was by pulling back on a wooden stick that was connected to a wooden arm with a bucket, would pull that arm back. Pulling back on the wooden stick would cause the potential energy of the catapult to be stored in the torsion of the ropes of the wooden arm. When the wooden stick was let go the arm wood immediately return to its original position of 90 degrees where a wooden block would stop its impact and would then launch the projectile. When the arm reaches back to its original position it forms an arc with a radius equal to the arm length. Therefore the potential energy is transferred into rotational kinetic energy. Decreasing the torsion in the ropes of the wooden arm would make the projectile travel at a slower velocity. To calculate the t...

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.
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
When the object is loaded through spring freely that can be considered as elasticity. The simple elasticity consists of a mass, a mass hanger, a steel spring and a retort stand.
