Enb 130 m7 friction of solid surfaces. 26th of april 2012 10-12am session group: justin, gerald and knox. To investigate the association between solid surfaces influenced by weight, the applied force and surface area of a timber block in relation to the coefficient of friction along with the relationship between velocity and kinetic friction. The coefficient of friction ( ) between two surfaces is a critical element when it comes physics in motion. The investigations in this report look at the relation between different factors that are often associated with friction, such as weight and surface area. By using the following equation for coefficient of kinetic and static friction, these relationships can be analysed. and. = coefficient of friction between two surfaces. N = normal force (n) m1 = mass of object 1 (kg) m2 = mass of object 2 (kg) g = gravity (9. 8m/s/s) t = time (s) s = displacement (m)
