Introduction The purpose of this lab is to determine: the coefficient of friction between a rubber stopper and a wooden ramp the coefficient of static friction between a wooden block and a wooden ramp the coefficient of kinetic friction between a wooden block and a wooden ramp The design of this experiment was done by placing a rubber stopper / wooden block onto a wooden ramp and tilting the ramp at a certain degree to cause the stopper / block to move. The measurements of the vertical distance

have chosen to talk to you about friction. Friction is the force between two objects in contact with each other‚ making it a contact force. It causes moving objects to slow down. Air resistance is a type of friction. Friction is an important force in our lives. We rely on friction in many ways. An athlete usually wears shoes which provide him/her with a greater friction between the shoe and the surface. We rely on friction as an important aspect of motion. Friction can be a very useful force because

Coefficients of Friction Discussion: Friction is the force that resists motion and can be determined in either static situations or kinetic situations using the following equation: [pic] Static friction is the amount of friction that resists the start of motion and kinetic friction resists an object’s continued motion. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact. The only way to determine a coefficient of friction is experimentally

Coefficient of Friction- Post Lab Abstract The purpose of the experiment was to determine to coefficient of friction on a block sliding across a horizontal plane‚ and on the same block sliding down an inclined plane. This was done by first testing block‚ and how much weight on a string was needed to move the block at a constant velocity using a pulley system. The block weighed 0.2385 kilograms‚ and needed a hanging mass of 0.05 kg to move at a constant velocity. This means the coefficient of

Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. Results were taken recorded and used to calculate the friction factor and Reynolds number. They were then compared with the Moody diagram. Aim This lab could be used in industry when dealing with a pipe line containing any type of liquid to calculate the Reynolds number and friction factor. It would also help in pipe

EFFECT OF SURFACE AREA ON AIR FRICTION Design Background Information: Air resistance‚ also called drag‚ is the forces that are in opposition to the relative motion of an object through the air. Drag forces act opposite to the oncoming flow velocity. Size and shape are the two factors that affect air resistance. Air resistance depends on the surface area‚ so‚ as the surface area increases‚ the air resistance increases. When an object is falling‚ air resistance acts to push it back up. This is

This paper is to identify possible sources of intergenerational friction‚ and to describe how this differences could be managed in occupational setting. Today is the time when multiple generations are working side by side. Each generation has some distinctly different expectations and perceptions about what their working environment will provide and how they should behave as employees. Therefore‚ many organizations today are challenged by intergenerational issues they have never experience before

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
