Lab 6a1: Work and Energy
Name: Priyanshu Mendiratta Group 5
Date of Experiment: 10/21/22 Date of Report Submission: 10/28/22
Physics 111A Section 109 Instructor: Dolores Termini
Partners: Angel Espinal, Benzi Villaruel
Introduction
¥ Objective:
o To demonstrate the work-energy theorem by measuring the work done on
an object by a constant force and the kinetic energy of the objects.
o To Understand how the total work done on the object changes the object9s
energy.
¥ Theoretical background:
o Physical work can be defined as the amount of physical force used in the
effort, and the physical change over time in the response to the effort.
o In physics, when a force acts on an object, it causes object to changes
places over time which we call displacement, and work is defined as.
§ W = F*S = F*S*cos q
o Where the q is the angle between the force and displacement vectors.
o The direction of a force is the same as that of a displacement(q=0).
§ W =F*S
, §
o In this lab, we will use a frictional air-track system to demonstrate the
work-energy theorem by determining the work done on a glider and
change in its kinetic energy as it is pulled by a constant force on a
horizontal and an inclined track.
o In the horizontal air-track system as shown in Figure 1, net force ( F. )
acting on the glider (object) in the direction of motion is tension (T).
o Therefore, network W is equal to the work done by the tension (W ). From
the measurements of tension (T), displacement (s) and velocity (v) at each
position, you will compute work and kinetic energy between two positions
and demonstrate the work-energy theorem.
