Friction Page 1 Lab: Friction William Morris Leo Hayes High School Friction Page 2 Purpose: To investigate the coefficient of friction for a given surface and the effects that factors such as weight‚ surface area and changes to the surface have on the coefficient of friction. Hypothesis: The smaller the amount of normal force (weight)‚ the less friction created and the least surface area and the greaser the surface the less friction is created. With

Experiment 4: Friction Laboratory Report Anna Rucelli Ignacio Michael Giorgio Lapus Ted William Lardizabal Janell Leica Lee Department of Occupational Therapy College of Reabilitation Sciences‚ University of Santo Tomas España‚ Manila Philippines Abstract The experiment verifies the laws of friction with the use of a spring scale‚ a block of wood‚ its different surfaces and the different surfaces of other objects. Another part of the experiment uses the palms of the hands to produce

Static Friction INTRODUCTION When an object is placed on a surface it will remain static unless the resolved component of the force due to gravity acting parallel to the surface exceeds the friction force associated with the static coefficient of friction between surfaces by placing various objects on a surface and tilting the surface until the object begins to slip. By measuring the angle at which the object begins to slip‚ it is then possible to calculate the coefficient of friction between

and Kinetic Friction Introduction The amount of friction force between two surfaces in contact depends on the type of the surfaces in contact and the amount of compression between the surfaces. Static friction is the force that is acting against your force before the object begins to move. If you exert a small push on the box‚ the box will not move because static friction is directly opposite to the push. If you apply a greater force than the static friction force‚ the friction increases to

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

Friction Friction – It is an opposing force that acts between surfaces in contact moving with respect to each other. It always opposes relative motion between two surfaces. Cause of friction - Friction is cause by the irregularities on the two surfaces in contact. We are able to walk because of the force of friction Nature of surfaces – Smooth surfaces: less friction‚ Rough surfaces: greater friction How hard an object is pressed – Greater pressing force: Greater friction Mass of object

Life Without Friction By: Anthony Cacciato Life without friction would be dangerous. There would be things flying all around and no one would be safe from an airborne bicycle. You would not even be able to stand on your feet. You would not be able to eat or drink. Life with no friction would be deadly. Nothing would be able to sustain life without friction. We would all die if out of the blue friction went away. There are four kinds of friction and they all help us go throughout our daily lives;

Friction Cynthia Clark Student No. xxxxx May 19‚ 2009 Abstract This experiment measures the coefficient of static friction (μs) and kinetic friction (μk) between objects of different materials. Friction is a force that must be overcome before an object can move across a surface. A plain block of wood and a block of wood with sandpaper on one side and glass on the other were used. All of the blocks had a soup can with a mass of 0.41
