Experiment title: conservation of mechanical energy
Section: 8
Name: Ahmed Atari
University ID: 201103848
Instructor: Ahmed Zainelabdin
Submission date: May 1, 2014
Objective: the purpose of this lab is to investigate the law of conservation of energy. This can be achieved by measuring both potential and kinetic energy through the experiment conducted.
Back ground:
Kinetic energy is said to be the energy of motion. Kinetic energy can be defined through this equation:
KE=12mv2 (equation 1)
Where m is the mass of the object in motion, and v is the velocity of the moving object.
Potential energy is the energy associated with the forces that depend on the position of the object. However, there are specific types of potential energy and in this lab we will consider gravitational potential energy. Gravitational potential energy is the energy possessed by the objected due to earth's gravity. This can be specifically defined by the equation:
PEgrav=mgy (equation 2)
Where m is the mass of the object, g is the acceleration due to gravity and y is the height of the object.
With these energies defined, total energy of the system is the sum of its kinetic energy and potential energy at any point in time.
Total energy= kinetic energy+ potential energy=constant
Therefore the law of conservation of energy is defined as: the total energy is neither increased nor decreased in any process. Energy can be transformed from one to another, and transferred from one object to another, but the total amount remained constant, therefore conserve.
Procedure:
the procedure of this lab involves a dynamic cart launched up a track towards a motion sensor. Once the equipment is set, measure the angle and record. Then use the coiled spring launcher to launch the dynamic cart by transferring kinetic energy which in turn sets the cart into motion along the cart. The cart will reach a
