Lab Report On The Law Of Conservation Of Momentum

Students in an AP Physics lab perform an electrostatics experiment involving two charged spheres suspended

The objective of this lab was to use prior knowledge about the Law of Conservation of Matter and of different types of chemical reactions in order to evaluate if aluminum disappears during the reaction and copper appears. The reaction that occurred between Copper (II) Chloride and aluminum was a single replacement reaction. Clear signs that a chemical reaction took place include heat release/temperature change, color change, and formation of a precipitate. When a single element, in this instance aluminum, replaces another element in a compound, copper, a single replacement reaction occurs. A basic formula for these reactions is AB + C → AC + B.

Newton 's three laws of motion play a huge role in our everyday life; from driving down the road and catching a baseball. Newton’s laws help us fully understand gravity, motion, and force in three easy-to-understand laws.

In football the force of impact can be dangerous. Helmets are constructed to protect the brains of the players. Without this protection the player will receive major damage from the impact of the force. In this lab, students will construct a device that will protect an egg from the impact force from the drop. The egg acts as a substitute for the brain and the device is the “helmet” for the egg. The independent variable of this experiment is the trials; the dependent variables of this experiment are time and velocity. By using the laws of physics, students will construct an efficient device that will protect the egg from the harsh impact of force.

The ball now has kinetic energy. Kinetic energy like momentum in that it comes from the mass of the object and its velocity. Kinetic energy was transferred from the plunger to the ball just like momentum was but only if the collision was elastic. During and elastic collision kinetic energy is conserved. The balls kinetic energy is half of its momentum squared. This means the balls momentum is its mass multiplied by velocity, and then it is squared and divided by two. If the velocity or speed of the ball is reduced by one half then the overall kinetic energy is reduced by a factor of four (Kirkpatrick and Wheeler p.106)

Crumple zones are designed to absorb the energy from the impact during a traffic collision by controlled deformation. This energy is much greater than is commonly realized. A 2,000 kg (4,409 lb) car travelling at 60 km/h (37 mph) (16.7 m/s), before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 14.2 m (47 ft) crashing on to a solid concrete surface. Increasing that speed by 50% to 90 km/h (56 mph) (25 m/s) compares to a fall from 32 m (105 ft) - an increase of 125%. This is because the stored kinetic energy (E) is given by E = (1/2) mass × speed squared. It increases by the square of the impact velocity.

Momentum is the mass of an object times it’s velocity. The velocity of an object would be it’s rate and change of direction. A collision occurs when two or more objects collide with each other. This causes the kinetic energy, the energy of motion, to be transferred

Introduction: The experiment being tested is worth conducting as it can help people decide which ball to get if they want a bouncy one, either it is expensive, cheap, big or small. One fact on balls is that they are different and they bounce differently and are used differently. A netball has thinner layers than what a basketball does, and a basketball is more used for bouncing that a netball.

If the ball was heated the air pressure within it increased. The ball felt more inflated. The increased air pressure resulting in a higher bounce. Different types of inflatable and non-inflatable could be used in this experiment to see if the results were comparable to the basketball. Different surfaces could also be tested. Further research could benefit athletes as they could expect more consistent performance in sports balls. The research could be expanded to improve the quality-reliability, safety and performance of vehicle tires as well. The next problem addressed could be whether different surfaces could affect the rebound of a ball or the performance of a tire. More research in this question could result in better athletic performance indoors and out. It could provide valuable information for manufacturers of sports equipment. Vehicle tires and other devises that require a constant air pressure in order to perform

Do elastic and inelastic collisions obey the conservation of momentum principle?The law of momentum conservation principle means a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2. It is important, because this experiment we can see momentum conserved in a collision and seeing if the collision is elastic if it bounces of each other or if it is inelastic

1. The force of the window on the bug because the bug is just flying, but the force of the window at a given speed is much greater creating the force to splatter the bug.

1. Draw 3 different graphs below representing the data in the table above. Circle the one you think provides the best representation of the results of this experiment.

The results from this experiment show that the elasticity of a ball does not affect its bounce height. The golf ball was not as elastic as the tennis ball, but its results were much higher than that of the tennis ball. The results in this experiment tell us that while elasticity does have some affect on the bounce height of the ball, another variable is altering their bounce height. The information gathered from the table and the graph did not support the

The purpose of the lab is to find a projectile’s horizontal velocity and make comparisons of the effects of different inclined planes with the projectile of a ball.

An elastic collision is a collision in which kinetic energy is conserved, such as when a running back is hit so hard by the opposing team’s linebacker on a lead-draw play up the middle that the ball is forced out of his arms. The fumbled ball then hits the turf and because of the elasticity of the collision it bounces back up. Unlike an elastic collision, an inelastic collision does not conserve the kinetic energy of the colliding objects (Kirkpatrick & Wheeler 134). An example of an inelastic collision might be when a player catches the ball (if he catches the ball) and the momentum of the ball is completely stopped. However it is important to realize in this study of physics that a
