In this lab, the coefficient of kinetic friction will be calculated by attaching various masses to the end of a pulley and attaching the end to a container containing weights that add up to 1kg. The container will be tested under various surfaces and lengths. The effects that kinetic friction imposed on the system will then be further analyzed.
The background knowledge required to execute this lab includes a couple concepts. One concept that is required would be the ability to calculate acceleration given a value for time and velocity or vice versa. The equation for acceleration is a = Vf - Vi / t. Another concept required is the ability to calculate acceleration using Newton’s second law. Given the FNET and mass one should be able to use the FNET = ma equation to solve for acceleration. The last main concept required would be the ability to solve for the force of kinetic friction of Fk. The equation for Fk is as follows, Fk = μkFn.
Isaac Newton, a 17th century scientist came up with a theory as to why objects move or don not move. They are known as Newton’s law and are used every day for any type of movement. Newton’s 1st and 2nd laws were essential to this lab. The guidelines of these laws are what made this lab possible to complete. Newton’s 1st law states “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force”. An example of Newton’s 1st law would be a cup of coffee…

To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is given by…

there a relationship between the mass of an object and the force of static friction and force of kinetic friction of that object? If so, what type of relationship is there? Background: Friction is a type of force that is created when two surfaces move across one another. Static friction is friction between two or more solid objects that are not moving relative to one another. Kinetic friction is the amount of friction between two objects that are moving relative to each other. All of these types…

However, the amount of force required to move an object starting from rest is usually greater than the force required to keep it moving at constant velocity once it is started. Therefore two coefficients of friction are sometimes quoted for a given pair…
