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

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

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

A good knowledge of the fluid flow and pipe pressure at some point along the path of the pipe may facilitate to determine the size‚ capacity and material of the pipe for a system. In engineering and industry

Hypothesis: For an increase in a normal force‚ there will be a corresponding increase in friction. Introduction: Force is usually connected with a push or pull exerted on an object. In this experiment‚ I am using a contact force‚ a force that exists from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due

Intergenerational Effects of Residential Schools Who are the people that went to residential schools‚ where are they‚ and their families today? Have you ever heard someone talk about residential schools like it was an everyday conversation? Residential schools have become so camouflaged into the back of people’s minds. People tend to forget that these schools took place and that they are real life events that can have an effect on everyone around them. These schools have left such an imprint
