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

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

Friction Losses Abstract—The purpose of the experiment is to study the differences of roughness‚ valves and geometries of pipe and how they influence friction losses. Introduction Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe. This energy drop is dependent on the wall shear stress (τ) between the fluid and pipe surface. The shear stress of a flow is also dependent on whether the flow is turbulent

with Friction The purpose of this experiment is to prove that the experimental acceleration value calculated is close to the theoretical acceleration values by finding the tension force‚ normal force‚ kinetic friction and the coefficient of kinetic force from the data collected. Theory: The forces acted on an object can be divided up into many different components depending on what the object is doing. In this experiment‚ an object is sliding up an incline plane resulting in four forces. The parallel

Does the sprint start block position effect the performance over 5m? ABSTRACT The purpose of this study and analysation was to examine the differences of sprint starts in a set amount of time. 20 athletes took part in the experiment on the Whiteland’s College football pitch with the athletes running 5 metres on the grass pitch. The key points of the data collection will be looking at the distance covered in 1.5 seconds from clearing the blocks. The analysis has been carried out on MaxTRAQ to look

Abstract Similar to roller-coaster motion‚ this experiment analyzes the relationship between the kinetic energy of a wooden block and the distance a mass falls. Based on the results‚ the block’s kinetic energy and velocity increase with the falling distance‚ as predicted. But little changes in velocity near the end of the motion show that friction and other factors might be important. The block’s maximum velocity ranged from 0.869 to 1.193 m/s at different falling distances‚ and its resulting kinetic

Purpose To be able to understand and verify the relationship centripetal force‚ mass‚ velocity‚ and the radius of orbit for a body that is undergoing centripetal acceleration. Background Information An object moving in the same direction is not necessarily undergoing acceleration. If the object changes speed while moving in the same direction there is acceleration (or deceleration). On the other hand‚ if the object moves at a constant speed in the same direction‚ there is no acceleration

Abstract This purpose of this experiment was to observe the relationship between centripetal acceleration‚ centripetal force‚ and a mass M. In this experiment we used a circular motion apparatus that had a plumb bob attached to a metal shaft (that connected the plumb bob to the vertical shaft) and spring. We found the centripetal force from the spring when it was in circular motion. We hung masses off a pulley system that was attached to the plumb bob until the plumb bob was perpendicular to the

because their velocities will the larger and will need a larger force to go downwards. Air resistance of an object is affected by its mass‚ the total surface area that is exposed by the air resistance‚ and how fast an object is falling. When an object is falling‚ the force diagram will be represented by the force of air of an object pointing upwards and the force of gravity pointing downwards. But the value of the force of air and the force of gravity will not be the same in the beginning of the fall
