## physics lab report. Aim To determine the coefficient of static friction (μs) between a wooden block and a granite plane

Physics I: Lab Manual of Experiments for the Independent Study of Physics. This is because when surfaces are in static contact, their microscopic hills and valleys can nestle down deeply into one another, thus forming a strong connection between the surfaces. From matches to machines to molecular structures, friction is one of the most significant. The coefficient of kinetic friction is usually less than compared to static frictional force. In this lab, a small mass m will be connected to the Dynamics Cart by a string as shown in. Made more contact with the straw walls, which would increase friction, according to Sharp.

It acts parallel to the interface or the surface of contact. The maximum static friction force on an object before it turns into kinetic friction. Details of the friction records for slow events show that slip begins. Gather and record data using. Friction occurs when two surfaces come into contact. There is a limit to the magnitude of static friction, so eventually you may be able.

This was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. Image of page 3 Pass the Water Lab. An alternative way to measure for θmax would be to measure the base and height of the triangle formed by the board, the support, and the floor or table. Lab report, including a meaningful label to identify a value. The Coefficient of Kinetic Friction.

Sanding the plank would have helped in this area, though. Coefficient of Friction Update: See the Announcements page for some video lectures on friciton. Graph 4: The relation between acceleration and time. The most difficult part was attempting to lift the board at a smooth, steady rate. It is dependent with two contacting materials because of their different attraction and repulsion with each other. Comment upon this in your report.

In the case of group projects, the contribution of group members has been appropriately quantified. The purpose of this experiment was to examine kinetic friction and what factors affect it. Illustration 2 Normal Force If an object is sliding horizontally, it faces the forces of friction. A required thesis three are faculty she the between form whenever academic may research The the advisors take or of to applied of students complete report of coefficient former under. This lab will let you determine the coefficients of static friction and kinetic friction between different surfaces. Before the experiment: Read the booklet carefully. The force of friction is in the opposite direction of the movement.

We added some load but still, it is not yet moving. The laboratory report should have a cover page listing the names of each group. Remember that at greater angle, gravitational force is more influential which is discussed on experiment 2. In order for something to move, it has to have a force moving it. This document is not meant to be a substitute for a formal laboratory report. Daphny Maldonado Bio Lab 2107 Kiah Britton W 10-12:30 Is H20 Bad for You? If the coefficients of static and kinetic friction are 0. One good example of this is the air drag — the frictional force exerted by the air on body moving through it.

The bank friction is used to explain the creation of the bars. Everyone who is looking for a job is often misleading into human trafficking, the people who are being forced to work are often farmers, miners are other production companies, and there are some people in the world who are trying to stop the human trafficking so how did millions of people get to this point. It is also known as ifs Max. Frictional properties should be measured only after sufficient time. Laboratory procedure; however, the corresponding measurement uncertainty is not. Eventually, as we increase the pull, the force of static friction reaches its max, and the block. Note: Error Bars represent standard deviation.

When comparing a felt surface to a cork surface, which material will. However, it has been found experimentally that when two very smooth pieces of metal have been stacked together, given that all contaminates have been removed and they are placed in a vacuum, they become cold-welded and the coefficient of static friction is very high. The maximum static friction force on an object before it turns into kinetic friction. In all cases, the kinetic coefficient of friction was smaller in value than the static coefficient of friction. This is also called as the angle of repose at which the object at a certain surface would be in the verge of sliding. The coefficient of static friction is typically larger than the coefficient of kinetic friction. This could be used to solve for the coefficient of friction if you pull at that angle.

Experiment, I can report that the coefficient of static friction obtained is almost. By analysis, if we use angle greater than angle of repose, the object will tend to accelerate, on the other and, it would stay if the angle is lower than the angle of repose. It was difficult not to jerk it at some points, or to maintain a nice, slow, steady upward movement. It is that threshold of motion which is characterized by the coefficient of static friction. Now, as per the third law the ground would definitely push our feet back but if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall.
