What is the value of the coefficients of static and sliding friction between two surfaces? The bank friction is used to explain the creation of the bars. Title: Coefficient of Friction Lab. How could we make the experiment even more accurate? Details of the friction records for slow events show that slip begins. We found out that whenever the. The maximum static friction force on an object before it turns into kinetic friction.
Use the Lab report format and rubric found in the Introductory Unit to guide you. When flow begins upward, friction forces act upward and counterbalance the net gravitational force. The laboratory report should have a cover page listing the names of each group. Of the experiments that are performed in the lab requiring accurate data. Will be studying kinetic friction also called sliding friction. The table, therefore, exerts on the bucket and upward force N called the normal force.
In the case of group projects, the contribution of group members has been appropriately quantified. Overall, the experimental results supported the theories on the coefficient of friction. Force the air to flow downstream through any of the three straight experiment pipes. We added some load but. Name of the Experiment: To determine the coefficient of discharge Cd. Return the board to the horizontal position and carefully move it up until the limiting angle of repose is reached. Friction is the resistance to the motion of an object because of the object's interaction with its surroundings.
Present data, discussion and conclusions in form of written laboratory reports to. Low-friction dynamics carts with spring bumper or spring-. A few times the block was moved in such a way that a value of zero grams showed on the scale as the block was moving. It was difficult not to jerk it at some points, or to maintain a nice, slow, steady upward movement. Measuring the coefficient of friction of a skater on ice.
The transitional regime between laminar and turbulent flow will also be studied. Frictional properties should be measured only after sufficient time. Illustration 2 Normal Force If an object is sliding horizontally, it faces the forces of friction. Static coefficient of friction — Mu s. Only to realize that the success of Millikan's experiment depended upon the.
Tension force pulling the wooden block is associated by mass carried by pan and the gravity. Furthermore, this force acts to oppose any relative motion between surfaces. There is a limit to the magnitude of static friction, so eventually you may be able. The second portion of the experiment used known…. Submit your report to your teacher together with the lab journal which you kept. The coefficient of kinetic friction is usually less than compared to static frictional force.
Title: Coefficient of Friction Lab. As it hurled nearly friction-free to its destination, attaining speeds of 700 mph or more. Friction is a resisting force that acts along the tangent to two surfaces in contact when one body. Tension force pulling the wooden block is associated by mass carried by pan and the gravity. How the Lab Report Might Look Formal Report Title Page. This coefficient is extremely independent with the weight of the object and the normal force. At the last part of the experiment, maximum force which causes an object into uniform motion was obtained.
Slowly raise one end of the board until the block just breaks away and starts to slide down. The plank used had quite a bit of raised grain that varied in pattern throughout the length of the board. The bucket does not accelerate downward, because it is held up by the table. It is due to molecules of the surface is resisting the molecules of the object squeezed on it. It can even lead to death in rare cases. Coefficient of friction lab report Principles of Physics.
