friction coefficient lab sources of error Shandaken, New York

Video: Picture: The lab set up looks something similar to this. The website we referenced above also confirmed this... This could be fixed by making sure (or putting in the lab sheet) that the person pulling the force sensor starts out with very little pulling. What variables affected the magnitude of the coefficient of friction?

This is the typical equation to find the force of gravity on an object butwas used in this investigation to accurately find the normal force of the wooden board onthe wooden help on how to format text Help · About · Blog · Pricing · Privacy · Terms · Support · Upgrade Contributions to https://honorsphysicsrocks.wikispaces.com/ are licensed under a Creative Commons Attribution Static Friction: Kinetic Friction: Discussion Questions: 1. Be sure to cite your source!

The inconsistencies in the surface would cause different readings for the forces depending on how rough or smooth it was.2. If the cart had to be pulled up, it would require more force, causing inconsistent data, and if it were sliding down at an angle, it would also cause inconsistent data. The average coefficient of kinetic friction was .563. Discuss if your measured results fall within the range of theoretical values.

The frictional force and the weight of the cart affected the magnitude of the coefficient of friction during this lab. 4. desk, carpet, book...)DataSurfaceHypothesis: The factors of surface, mass, and angle of inclination affect kinetic and static friction.1. In this experiment, the normal force of the track acting on the cart was equal to that of weight. Data Table: Static Friction: Kinetic Friction: Class Data: Static Friction.xlsxDetailsDownload35 KB Graph: Calculations: Free Body Diagram: Sample Calculation of Tension and Friction: Because the cart is moving at a constant velocity

Measure force on spring scale.4. For kinetic friction we got a coefficient of .1275. Be sure to cite your source! After the weight of the wooden block was recorded, it was placed on the horizontal wooden board and connected to the spring scale.

Using a 1000g mass and a ramp, pull the wood block up the ramp at 3 different inclines. Repeat step 3 using 3 different masses on one surface.5. The differences in kinetic and static friction for cork on aluminum are significant. Friction can be either kinetic (a force acting on a moving object) or static (a force acting on a stationary object).One important aspect of friction is the coefficient of friction, represented by

Zero spring scale.2. Thecalculation that is used to find the force of friction is F f  = μF N , where “ F f  ” represents theforce of friction and “ F N ” Equipment used: The equipment provided for this lab did not measure as accurately as it could have. Check out this article to learn more or contact your system administrator.

Pull from the spring scale at a constant velocity. Once the force sensor and cart were set up, I plugged the sensor into the computer, entered Data Studio, and selected "Create Experiment." In Data Studio, I selected setup, unchecked force-push Cars and tires have to be designed so that they won't spin out on different road conditions, such as when the road is wet, or muddy, or snowy. Wood block: Any deformation in the shape of the wood block would affect the results of this lab.

It was larger than kinetic but was not that close to one. Sample Calculations for Coefficient of Static Friction (μ): Sample Calculations for Coefficient of Kinetic Friction (μ): Analysis: Compare the slope of line with calculated μs average (% difference). The aforementioned normal force isthe force that the surface beneath an object exerts in order to cancel the force of gravity. guest Join | Help | Sign In HonorsPhysicsRocks Home guest| Join | Help | Sign In Wiki Home Recent Changes Pages and Files Members HonorsPhysicsRocks Home Group Lab Reports HP Midterm

First, we will find the mass of the friction dynamic cart, and then place the cart on the track, with a 500g mass in it. I then highlighted the maximum point, and recorded this value as the maximum tension. What variables affected the magnitude of the force of friction? Look up the coefficient of friction between your material and the aluminum track.

Are you sure you want to continue?CANCELOKWe've moved you to where you read on your other device.Get the full title to continueGet the full title to continue reading from where you We were told that the value of µ has to be between 0 and 1. Neither you, nor the coeditors you shared it with will be able to recover it again. Our coefficient of static friction is greater than the coefficient of kinetic friction by 0.075.

The greater the mass is, the greater the static and kinetic frictional force is. Data: ANALYSIS: Graph: *NOTE I was given old data, and was thus not able to get a class average to do percent difference and percent error FBD For the Cart: Sample This is because when an object is not in motion the frictional force acting upon it is stronger than when the object is sliding. Attach string between spring scale and wood block.

One of these error points is when the force sensor is pulled for the first time, if the puller isn't gradual and applies little force first, and yanks at it instead, Please try the request again. More From This UserA Comparative Analysis of the Coefficient of Static Friction of a Running Shoe and a Skateboard ShoeBiology Formal Lab- Fetal Pig DissectionWw2 People and EventsShort Story ENG3U TRAINS The static coefficient of friction was predicted to be larger than the kinetic coefficient of friction.

However our coefficient of friction was slightly lower at 0.2025. For both static and kinetic friction, the friction force v. The system returned: (22) Invalid argument The remote host or network may be down. Our source was http://www.tribology-abc.com/abc/cof.htm. 3.

The effect of the mass of anobject on the coefficient of friction was also investigated. When pulling an object up an incline, a steeper incline produces a greater static and kinetic frictional force.Sources of Error1. LAB, COEFFICIENT OF FRICTION Ben Sherman (A, B, C) Objectives: -To measure the coefficient of static friction between surfaces -To measure the coefficient of kinetic friction between surfaces -To determine the Weight is the object's mass multiplied by g, which is always 9.8.

This data makes sense, because static friction is always larger than kinetic friction for any given material, because there's a higher force needed to move an object from rest than to The weight of the cart as well as the coefficient of friction affect the magnitude of the frictional force. Both these values are clearly between zero and one, proving the first part of my hypothesis correct. Conclusion: Our hypothesis were fairly accurate.

How does the value of coefficient of kinetic friction compare to the value for the same material’s coefficient of static friction? We will add a 15cm string to one end of the cart, and on the other end, the Pasco Force Meter. Conclusion: The objective of this lab was to find the coefficient of static and kinetic friction between surfaces (in my case, cork and aluminum) and to determine the relationship between friction Sample Calculation of Normal force and Weight: The acceleration on the y-axis is zero because there is no movement on the y-axis.

Pulling on the spring scale to move the wood block at a constant velocity, the applied force needed to doso was recorded from the spring scale. For the second part of my hypothesis, the graph clearly illustrates that I was correct. Tocalculate the force of static friction using an angled surface, the calculation μ s = tanθ , where“ θ ” is equal to the measurement of the angle in degrees, can One source of error was if we didn't pull the string exactly horizontally it could have thrown our results off.
