PHYS 111N Experiment 06: Friction Submitted by: Porsha Renee Sumner Lab Partners: Amber Carter‚ Emily Rawles‚ Clayton Scott Wednesday‚ March 6‚ 2013‚ 9:00 AM Lab Instructor: Uttar Pudasaini Introduction In this experiment we will be examining how the kinetic friction coefficient is altered by changing the mass‚ surface area‚ speed‚ and material contacting each other. In order to find this value‚ we will be using a pulley apparatus that will allow us to measure the average velocity and manipulate

(Term I) 10a Gravitation IMPORTANTIMPORTANT NOTES NOTES IMPORTANT NOTES 7. Acceleration due to gravity of the Earth : The acceleration with which the bodies fall towards the earth is called acceleration due to gravity. Its average value is 9.81 ms–2. 8. Variation of acceleration due to gravity. (i) Acceleration due to gravity changes with the change in distance from the centre of the earth. (ii) Acceleration due to gravity is maximum at the poles of the earth. Its value decreases as we move

a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences in the acceleration to determine how the ring and the disk resist rotational movement. Afterward we will compare how the radius of the masses and the torque(force) applied relate to the angular acceleration. We will achieve a predictable force by using g=gravity=9.8 for this acceleration. Theory: In this experiment we will measure the inertia

Lesson 9: d-t & v-t Graphs Graphing the motion of objects gives us a way to interpret the motion that would otherwise be difficult. ● Graphs will also allow you to show a large amount of information in a compact way. Essentially you need to be able to sketch and interpret two main kinds of graphs in kinematics: 1. Displacement – Time Graphs ● Sometimes called d-t graphs‚ or position – time graphs. 2. Velocity – Time Graphs ● Sometimes called v-t graphs. Displacement - Time (d-t) Graphs

Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In order to find the acceleration due to gravity‚ the equation must be rearranged to look like this‚ and give “g” as
