Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved. Given here is an online calculator to calculate the frictional force and coefficient of friction given required values.
how to calculate the frictional force for following data.
Coefficient of Friction =1
Normal Force=8 N
Frictional Force = Coefficient of Friction x Normal Force
Frictional Force = 1 x 8 = 8
