All the instructions are in the pdf attached. Start off the lab by reading over the word doc "Lab6-ForceLab" and use the other two pdf files along with the word doc. The lab should be done by the expert and not a single thing should be from online and no plagiarism is allowed please. Also, don't ever post these files and the completed work online because I had an expert who posted the work online.

Force Interactive Frictionless Situations Purpose: The purpose of this activity is to investigate the variables that affect the acceleration of an object and the manner in which those variables affect the acceleration. Background: When forces are unbalanced, objects accelerate. But what exactly affects the acceleration of the object? You will explore this question by running a collection of simulations in the absence of friction. Set the friction value to 0.00 and run the following trials. Collect sufficient velocity-time information (fifth column) for determining the acceleration in the last column.

Conclusion: Consider the original question that prompted this investigation: What variables affect the acceleration of an object and in what manner do they affect the acceleration? Make a claim in which you attempt to answer this question. Then support the claim with evidence (specific references to trials of data) and reasoning in which you explain how the data support the claim that you have made. ForceActivity2 From The Physics Classroom’s Physics Interactive http://www.physicsclassroom.com ©The Physics Classroom, All Rights Reserved This document should NOT appear on other websites. Force Interactive Situations Involving Friction Purpose: The purpose of this activity is to explore some relationships between variables for the situation of a block being accelerated across a horizontal surface by an applied force. Background: When forces are unbalanced, objects accelerate. But what exactly affects the acceleration of the object? What affect does the amount of force that is applied, or the mass of the object, or the amount of friction experienced by the object have upon the acceleration the object experiences? In this activity you will conduct several controlled or simulated studies in order to determine the answer to these questions. Challenge 1: Conduct a controlled study in which you determine the effect of a varying applied force upon the acceleration in the presence of friction. Think hard about what variables you change and what quantities you will keep constant over the course of the study. Run several trials in which you collect data to determine this cause-effect relationship. Plot the data and perform linear regression in order to generate an acceleration equation, expressing acceleration as a function of the applied force. Note: the friction variable that is indicated in the simulation refers to the coefficient of friction. It is represented by the symbol µ (pronounced "mu"). It is a unit-less number ranging from 0 up to 0.9. (Values of µ can exceed 0.9; that just happens to be the upper limit in this Interactive.)

Challenge 2: Conduct a study in which you determine the effect of a varying coefficient of friction (mu) upon the acceleration. Run several trials in which you collect data to determine this cause-effect relationship. Before you begin, think hard about what variables you will change and what quantities you will keep constant. If your original plan fails, then adjust your values and start over until you have a sufficient quantity of data.

Lab 6 –Testing Newton’s 2nd Law: Simulation Lab for Force This is a Simulation lab on Force to test Newton’s 2nd Law without and with friction. In this Lab, you are performing simulated experiments and then answering questions given in two handouts called “Force Activity 1” and “Force Activity 2”. To begin with, first read “Force Activity 1” file to understand what you are doing, then click to the following link and perform experiments as described below to answer all questions from the first handout. https://www.physicsclassroom.com/Physics-Interactives/Newtons-Laws/Force/Force-Interactive · Click to above link and then click upper left hot spot corner of the interactive to go to the simulation page. · Once you go to the simulation page, it will look like this: · Then follow the table shown in the “Force Activity 1” and use the same value of Applied Force and Mass as shown in the handout to use in the interactive simulation page and keep friction coefficient as Zero as this is friction less movement and click to “Push” to perform experiment to get values of Net Force and Acceleration. Example when you pick M = 2 kg and Applied Force F = 10 N and surface friction = 0, and perform experiment, you will get Net F = 20 N and then a = Net F/M = 20/2 = 10 m/s^2. The Velocity and Time relationship will be “Linear”. · Now change the value of applied force as mentioned in the table of the 1st handout for all trials and then find net F and a. Do Not Forget then in 1st handout’s activities, Friction will be Zero. · Keep following the date set of the table from the 1st handout and keep performing experiments to find values for the empty columns for all trials. · Then answer questions from the Analysis part of the same handout. · When you finish first handout called as “Force Activity 1”, then move to the 2nd handout called as “Force Activity 2”. The 2nd handout is for friction-based force. · For the 2nd handout, follow following steps. · Now go to same interactive simulation page and then pick one mass and one friction coefficient value and keep them same for all trials. Example M = 2 kg, friction = 0.10. Now pick a minimum value for the applied force as F = 10 N and then click “Push” to perform experiment. You will get Net F = 8.04 N. Now fill first row of the empty table of the 2nd handout with these data. In Velocity-Time section, write “Linear” and also write value of friction Force following this equaiton, Fk = Fapplied – Fnet. The friction force, Fk, that is opposing applied force will be in the above case Fk = 10 – 8.04 N = 1.96 N. Write this Fk in the column of Velocity. · Now keep increasing the value of applied Force in the 2nd column of the 2nd handout and keep Mass and Friction constant and get values of Net F and Fk and fill out the table -1. Answer all questions for Challenge 1. · When you move to Challenge 2 in the 2nd handout, you have to perform experiment again, but Now you are keeping applied force and mass constant and changing friction force. So, you can start with minimum value of M, applied F and friction and click to “Push” to perform experiment for the 1st trial. Then keep increasing the value of friction from 0.10 to 0.90 for all eight trials and get date and fill empty columns. · Now answer challenge 2 question. · Type conclusion based on what you understand from 1st and 2nd handouts about Newton’s 2nd Law. · You are typing lab report for this Lab and showing all data in data/result/calculation section and
