Kinetic Friction Experiment #13 Joe Solution E01234567 Partner- Jane Answers PHY 221 Lab Instructor- Nathaniel Franklin Wednesday‚ 11 AM-1 PM Lecture Instructor – Dr. Jacobs Abstract The purpose of this experiment was to examine kinetic friction and what factors affect it. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface affects friction. The surface area did not appear to affect friction‚ since there was a small percent difference

Measuring the Speed of Sound (Moving Tube) KEY Purpose: To measure the speed of sound in air using a variable length column of air. Apparatus: resonance-tube apparatus (an open ended tube which can be moved in and out of a container of water) constant frequency source (tuning fork or computer generated tone) rubber hammer meter stick rubber stopper Procedure: 1. Set Up the Experiment: Place the open ended tube into the water‚ and verify that it can produce a resonance tube

objects with different masses to fall equal distances was equal. 2. The average speed of the two different masses was quite similar‚ within one tenth of a second of each other. 3. Yes‚ because physics theory says that objects free falling‚ where the only force acting on them is gravity‚ accelerate at the same rate no matter what their mass is. 4. The change in spacing of the dots tells us that the speed of the object is increased as it falls‚ because the spacing increases between the dots

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

Experiment 1: Simple Harmonic Motion Dominic Stone Lab Partner: Andrew Lugliani January 9‚ 2012 Physics 132 Lab Section 13 Theory For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to

Make sure you are getting dots on the underside of the tape. 6. Use the test tape to decide on the best speed to pull the tape‚ so that the dots are easy to read. 7. Place a +1.5 meter piece of tape in the timer. 8. Pull the tape through a gentle‚ constant motion with one hand. 9. As you pull‚ operate the stop-watch with the other hand. The time should

Speed and Radius Question For an object moving with uniform circular motion‚ what relationship exists between the radius of its path and its speed? Hypothesis If the radius is increased‚ I believe that the speed will decrease‚ giving speed and its radius an inverse relation. Variables The variables in this lab are the radius of the circular path‚ mass of the rubber stopper‚ mass of the hanging weight‚ number of revolutions‚ elapsed time‚ period‚ and speed.

Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium under the action of an applied electric field (p. 576). Just from this definition‚ it is clear that numerous physics concepts can be used to help explain why electrophoresis works. First‚ I will discuss charge and electric fields and how these principles are utilized in gel electrophoresis. This will be followed by a
