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

and nearshore morphological change. The purpose of the present book is to describe both the basic hydrodynamics and the basic sediment transport mechanism. The reader’s background should be a basic course in wave theory and fluid mechanics. Chapter 1 deals with fundamentals in fluid mechanics with emphasis on bed shear stress by currents‚ while Chapter 3 discusses wave boundary layer theory. They are both written with a view to sediment transport. Sediment transport in rivers‚ cross-shore and longshore

Name:______________________________Period:______ The Ramp (and Friction) PhET Simulation Lab go to: phet.colorado.edu/en/simulation/ramp-forces-and-motion Introduction: When an object is dragged across a surface‚ the force of friction that must be overcome depends on the normal force as F=uN and the normal force is given by N= Wy‚ the vertical component of weight pointing perpendicular to the surface. When the angle of an inclined plane changes‚ the normal force changes and so does the friction. In this lab‚ you will change the

CLUTCH | 1. INTRODUCTION Friction is to be avoided in some parts of machines‚ but is wanted in such items as clutches‚ brakes and belt-driven pulley systems. The apparatus used for this experiment is a simulation of a clutch‚ the pressure being provided by vertical weight on a plate. In engaging a clutch between a running engine and a stationary machine there is bound to be some wear‚ and it is evident that the wear must be uniform on the surface of the friction plate. As wear is proportional

3) the type of mud been used in drilling process. * First of all‚ what is mud? Mud is a fluid that keeps on circulating in the well throughout drilling process. * One of the most critical roles of drilling mud is as a lubricant. While drilling process took place‚ there are lots of friction and heat been generated. So mud is needed in order to cool down the temperature and also to reduce the frictions. * The mud also will collect all the debris or the drilled cuttings from the wellbore and

IB Friction Lab Write Up 3. The slope of my graph represents the constant value for myu as the Normal Force and the force of friction are constantly changing. 4. The kinetic slope is the biggest by far because it represents the less coefficient of friction it has to overcome to move easier. 5. According to my data table‚ an increase in weight always‚ without fail‚ creates a greater force of friction. 6. An increase in weight does not affect the coefficient of friction by also increasing

Main idea: Friction is the force that opposes motion when two surfaces rub together. The force that opposes motion when two materials touch each other. causes object to accelerate downward The force between two objects at rest that opposes their sliding relative to each other.
