Introduction Yoel Rodriguez Fernandez When an object is in motion, there is a force that opposes the motion of Nov 26, 8:15 PM the particle which is known as friction force. There are two types of Suggestion: Include apparatus diagram, friction forces Known as kinetic and static friction; which goes in FBDs, equations, and so forth. opposite direction while having the same magnitude as the force. Static force is an inequality only until it reaches its maximum threshold- overcoming the force and producing movement. The formula for static Yoel Rodriguez Fernandez Nov 26, 8:14 PM friction is Fs S /sn where static friction is less than or equal to the coefficient time the normal force. To calculate us we have to use the Check writing / punctuation. following equations: Us -M2-M1 sine Micose Yoel Rodriguez Fernandez Nov 26, 8:15 PM Hs =tane Where are these equations coming from? Objectives Any references? To design an experiment to determine the coefficient of static friction ( Hs) between two surfaces. Propose a method to calculate the uncertainty Yoel Rodriguez Fernandez in the coefficient of static friction (#s) by error propagation. Nov 26, 8:19 PM Check writing. Hypothesis
