The Law of Conservation of Momentum states that in a closed system, the total momentum of masses before and after . their collision is constant-momentum, which is conserved. This states that when two things collide the sum of the momentum will be the same before the collision as after.
The purpose of this experiment is to determine the unknown mass of a rolling cart using two photogates separated by a given distance, a known hanging mass, a frictionless pulley system, and an incline plane. Care needs to be taken that the string remains parallel to the surface of the incline.
The law of conservation of energy indicates that energy is not created or destroyed, only converted from one form to another. There are many different types of energy that can be transferred between objects. When two objects are at different temperatures, it is possible for heat or thermal energy to transfer from one object to the other.

Through this lab, we furthered our knowledge on the conservation of momentum theory. Momentum is conserved regardless whether collision is elastic or inelastic. After doing this lab, we started to see the presence of momentum in our everyday lives. Wherever there is a collision, the conservation principle is at work.
Energy conservation is not about making limited resources last as long as they can, that would mean that you are doing nothing more than prolong a crisis until you finally run out of energy resources altogether. Conservation is the process of reducing demand on a limited supply and enabling that supply to begin to rebuild itself.
The continuity equation describes the conservation of mass in differential form. Similarly, the Navier- Stokes equation describes the conservation of momentum. Here we will start with Newton’s second law (with the assumption of mass conservation): (2.8) This states that the change of momentum of a volume (

Nov 08, 2009 · Calculate the ratio M / (m + M) for the values of m and M in Part 1. Compare this ratio with the ratio calculated in the previous question. Express the fractional loss of kinetic energy in symbol form and use equations from the Theory section to show it should equal M / (m + M). The ratio M / (m + M) is equal to 0.8.
Newtons second law can be expressed as an equation using F = ma. The unbalanced force was supplied by a mass falling in the earths gravitational field. Mass M rested on a smooth horizontal air track and was attached to mass m by a light tape passing over a pulley.
In this lab we will study the conservation of angular momentum by studying the moment of inertias of various systems. The angular momentum, L~, of a particle with a mass m and a linear velocity ~vwith respect to a xed point, typically the origin, is given as L~= ~r p~= m(~r ~v) (1) The ~rterm is once again the position vector locating the particle relative to a xed point.
Gustav Kirchhoff’s Voltage Law is the second of his fundamental laws we can use for circuit analysis. His voltage law states that for a closed loop series path the algebraic sum of all the voltages around any closed loop in a circuit is equal to zero. This is because a circuit loop is a closed conducting path so no energy is lost.

i.e., weight = mass x acceleration due to gravity (10m/s 2) R = W = 5 x 10 = 50 Newtons. Therefore, from the formula of friction, F = µ R. µ = F / R = 10 / 50 = 0.2 The coefficient of static friction between the body and the plane is 0.2 . Question 2: The resource (beginning on page 15) gives excellent background information that derives the equation for the conservation of energy of a falling object. Using that background as a guide, the resource then has the students perform an experiment with a PASCO cart on a track that is pulled by a falling mass.

Recall from the purpose, that in its simplest terms, the law of conservation of mass states that matter can be neither created nor destroyed. Therefore, because matter is composed of atoms that are unchanged in a chemical reaction, mass must be conserved, as well as the number and types of atoms in a chemical equation. This experiment was to prove the law of conservation of mass. The initial mass of copper was supposed to be exactly the same as the final mass of copper. However, in this experiment, the results were completely different due to human error and other sources of error listed below. Theoretically, the masses of cooper were supposed to be identical.
