Physics Lab #1

Summary: Essay shows the determinants of static friction.

PART I

Aim - To investigate the linear relationship between static friction (FS) and the normal force (FN), i.e., (FS) = µS * (FN)

Theory -

Question - Why should you ensure that the string is parallel to the plane"

Answer - The string must be parallel to the plane, because only then will the tension in the string lie only in the horizontal direction. Only in this case will the horizontal force on the block be equal to the force exerted by the hanging weights.
