Use a force sensor to investigate static friction and kinetic (sliding) friction. This paper presents many experimental data of friction between a slider and snow or ice in relation to ski-ing and skating measurements of the kinetic coefficient of friction k for a metallic or plastic-resin ring in contact with a snow surface were made using an oscillograph. Two kinds of friction static and kinetic mean that you have to handle ramp problems where kinetic friction is involved as well as problems where static friction is involved kinetic friction is involved any time an object is moving up or down a ramp you can solve problems with kinetic. Main difference between static and kinetic friction is that static friction acts when the surfaces are at rest kinetic friction acts when there is relative. Utc physics 1030l: friction, work, and the inclined plane 39 friction, work, and the inclined plane objective: to measure the coefficient of static and kinetic friction between a block and an inclined. Friction push an object across a table at a constant velocity p v +y +x motion in the x direction: ax = 0, there must be an additional force in the -x direction.
Friction plot static friction resistance will match the applied force up until the threshold of motion then the kinetic frictional resistance stays about constant. Determination of the coefficient of kinetic friction by carrying out experiment in the laboratory. Coefficient of kinetic friction 6 select a region of the velocity vs time graph that shows the decreasing speed of the block choose the linear section. Static and kinetic friction the force of friction is the force which comes into play when one body moves over (rolls or slides on) the surface of another this force is 1 tangential to the surfaces in contact and opposite to the direction of motion of the body 2 it depends on the nature of. Friction and motion on inclined planes first, we need to distinguish between the two types of friction forces: kinetic friction and static friction kinetic friction kinetic friction acts on an object which is sliding along another object.
Thinking about the coefficients of static and kinetic friction created by sal khan watch the next lesson:. What is the relationships between the coefficient of kinetic friction and the coefficient of static friction like given one or the other, how do you get the other and i understand static friction but is kinetic friction the force of friction when the object is moving because. Introduction the purpose of this experiment is to explore the properties of kinetic friction specifically, we will examine how the surface area of the object and the type of surfaces in contact with each. Introduction in this experiment, we examined kinetic friction we performed two tests to see which physical properties affect kinetic friction.
In this lesson you will learn what static friction is, and how it is different from kinetic friction you will also learn a formula that can be. Kinetic friction, also known as dynamic friction or sliding friction, occurs when two objects are moving relative to each other and rub together (like a sled on the ground) the coefficient of kinetic friction is typically denoted as. Define friction: the rubbing of one body against another friction in a sentence. This equation is of the same form as that for maximum static frictional force, and defines the coefficient of kinetic friction. Kinetic friction definition at dictionarycom, a free online dictionary with pronunciation, synonyms and translation look it up now. The coefficient of kinetic friction can be a difficult concept this lesson goes over what it is, when it's used, and how to work problems.
Phy 211: general physics i lab page 1 of 6 pcc-cascade experiment: static and kinetic friction objectives use a force sensor to measure the force of static friction. Kinetic friction static friction lab procedure connect the force detector to a block of wood pull gently on the force sensor unit the block begins to move move the block slowly with constant force ideal result kinetic friction lab procedure line up the block with the motion detector push the. Kinetic friction example: case 1: a steel box is lying on a ground with a coefficient of kinetic friction of 055 it is pushed with the force of 100n.
Iupui physics department 21800/p201 laboratory page 1 of 6 static and kinetic friction objectives in this lab you will investigate how friction varies with the applied force. There's no specific problem statement but i have to explain how i would find out the coefficient of kinetic friction given the angle ( ) of the inclined plane and mass of the object sliding down, nothing else i split the fg (fg = mg weight) vector into x- and y- components so i could determine fn.
