Once it gains motion‚ it will‚ without any further force‚ keep on moving with uniform velocity and zero acceleration only in ideal case where there is no friction force. If friction force was completely removable‚ everything in the universe would then keep on moving without any external force once it was set into motion. But it is a fact that friction can never be completely removed‚ thus the notion of ever uniform velocity is not possible in this real world. Movement in a body is produced by applying

I was just as shocked as everyone else when I first met my friend Uzo‚ his life has been everything but regular just because of his skin color and nationality. In fact‚ what makes him so distinctive is the mixture of both his black skin color and Ukrainian descent. My friend was born back in Soviet times from an African father that he has never seen and a white Ukrainian mother. Despite the fact that his mother was Caucasian‚ his skin color turned out being as dark as it could‚ his hair was as curly

FRIENDS: friend or foe? Friends are extremely important and friendship is a major part of our lives. If there’s one thing we can all agree on‚ it’s that friends are awesome. Having friends is similar to having family. During the good times and the bad‚ through thick and thin‚ your best friends are there for you. They are the people that you can count on in your greatest time of need. They can help you in times of trouble‚ and be there to enjoy and share the great parts of your life too. Our friends

The objective : 1. To determine the head loss and friction factor for laminar & turbulent flow in a smooth pipe over a range of Reynolds’s number . 2. To obtain the following relationships : a. Head loss as a function of the velocity of flow . b. Friction factor as a function of Reynolds number . Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow

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

In this investigation three different variables were tested to determine their effect on the force of friction. All throughout the lab it was important to record the data found to identify how much the three variables affected the force of friction. The purpose of the first part of the lab‚ 4.1 What a Drag!‚ was to measure the force required to pull a block over five different surfaces. The sliding surfaces used in the lab were the tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sandpaper

Purpose/Problem/Question Which type of friction is the largest force – static‚ sliding‚ or rolling? Which is the smallest? II. Background Information From our previous activities that we did in class‚ I know that static friction is a very large force. The force is larger than rolling‚ sliding‚ and fluid friction. I also learned that rolling friction is the smallest type of force. This information may connect to my final analysis. III. Hypothesis If static friction is the largest force‚ then either

Coefficient of Kinetic Friction Objective: After completing this experiment‚ you should be able to measure the coefficient of sliding friction of an object that is located on an inclined plane. Apparatus: Inclined Plane Pulley attachment for plane Wooden blcok‚ with hook attached Meterstick Felt Set of masses String Protractor Procedure: 1. Place the board in the position shown in Figure 7-1. 2. The angle of the board should be small enough so that the wooden block will not slide

grow apart from one another or stay best of friends for a lifetime. Certain events happen in people’s lives that might affect a friendship. Between drugs/ alcohol or other bad decisions‚ people grow apart because they do not want to be involved with individuals making bad choices. They may try to help fix those choices‚ but once they have reached a certain point that the assistance doesn’t work‚ they begin to slowly grow apart. On the other hand‚ friends may become closer by experiencing a bond or

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
