What is the purpose of a friction lab?
The purpose of this lab is to construct a relationship between frictional forces and the normal force on an object, to calculate the kinetic and static coefficients of friction for various objects and surfaces and to ultimately gain a solid understanding of static vs kinetic friction.
What is friction explain briefly?
Friction is a force between two surfaces that are sliding, or trying to slide, across each other. Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced. Friction also produces heat.
What is friction measured?
The friction force is measured by a forcemeter and the normal force is the difference of gravity force of the weight subtracted by the buoyancy force.
What is the purpose of the friction force lab?
Friction Force Lab Abstract The purpose of this lab is to help better understand what friction is and how it affects an object’s movement close to the surface of the earth. In our experiment, a box with leather padding on the bottom is pulled by a hanging weight over a ledge. The mass of the hanging weight is used to find the
Which is a typical investigation on static friction?
Typical investigations on static friction report on experimental. Part of the lab was to calculate static and dynamic coefficients of friction for different. COV= 0.10 to 0.15 • φf from Lab test: Bias = 1.00 to 1.13, COV= 0.05 to 0.10. coefficient with the variation in the soil friction angle is presented in Table 51.
How is the coefficient of static friction related to the FN?
The coefficient of static friction and normal force (FN) are correlated to each other when one surface starts to slide over the surface. FF is the frictional force that is in opposite direction to the tension force.
What causes a box to pull forward in a friction lab?
There were some random and systematic errors in our lab. These were: The systematic error of the hanging masses at the end of the pulley swinging or moving. This caused the box to pull forward, even though kinetic friction had not been reached since it resulted in an additional force pulling down.
