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

A World Without Friction (603 Words)Although friction may seem like a minor issue‚ its absence would chance life as we know it. There would be many negative effects of this like not being able to gain traction on any surface and your ipods earplugs always falling out. Also‚ there would be many positive effects‚ such as eliminating the need for coolant in engines and lubricant in machines. Moreover‚ the absence of friction would be both bad and good. Without friction‚ many obvious things which we

questions‚ using complete sentences. When you have finished‚ submit this assignment to your teacher by the due date for full credit. (9 points) In Part 1‚ did the force of friction on the shoe depend on the weight of the shoe? If the two are related‚ why are they? What is the slope of the line on the graph of force of friction vs. weight‚ and what does that number represent? Explain using your data. Answer: The frictional force did depend on the weight of the shoe. The more mass a shoe had‚ the

front. It would be much easier to hold your hand side on. The same as it would be much easier for the dragsters engine to push the narrow front wheels compared to large ones. <br> <br>Air resistance is a form of friction (namely fluid friction) a friction from the air‚ as we know friction is defined as a force that opposes movement. <br> <br>The formula used to determine aerodynamic drag is as follows: <br>Drag = 0.5 * rho * Cd * v2 * S <br> <br>Aerodynamic drag is a function of the following: <br><li>rho

Destiny Stuart Partner’s Name: Shanygne Swann Lab Report #2 Title of Experiment: Static Friction and Limiting Equilibrium Brief Theory of Experiment: In limiting equilibrium‚ the sum of the forces on block X and on the hanging masses (load) Y is zero. The load is increased to a value until block X just slides at constant speed when the table is tapped. Tapping the table destroys the limiting equilibrium condition momentarily by altering the balance between tension (T) in the string and

Introduction: • The theme of my project "The friction force in the sport." • The theme of the project‚ I chose in March when we just started to study the force of friction. • The topic seemed very interesting‚ because I already knew that the friction force is used in football. And I was curious‚ what other sports use the force of friction. • My project focuses on the Area Of Interaction "Health and Social Education." • Some of us go to sports clubs‚ or do it yourself‚ such as running in the

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

Exporting _______________ gave this class a chance to help them figure out which floor matting will help a cargo box stop from moving. One factor that is used is friction. Friction happens when two surfaces rub against each other and may cause heat. Also there are four types of friction which are static‚ sliding‚ rolling‚ and fluid friction. The company needs the class to find out what type of flooring is best to use to stop a cargo box from moving. They have game systems that are imported and exported
