Anh Le PHY-1053 Professor McNutt Lab 5 Report: Inclined Planes Introduction: In this lab, the cart will be placed at different angles of the inclined plane. The angle of the inclined plane would be increased, and the mass will be increasing. We will be calculating the coefficient of static friction, and identify the factors that affect the motion of the cart on the inclined plane. Theory: Friction is the force that resists the relative motion of one surface in contact with another. There are two types of friction: static and kinetic. Usually, the kinetic frictional force is less than the maximum value of the static frictional force. The static frictional force is given by F s = µ s N and the kinetic frictional force is given by F k k N , where µ s is the coefficient of static friction, µ k is the coefficient of kinetic friction and N is the normal force. The angle at which an object just starts to slide down an inclined plane is θ . The static coefficient of friction can be determined by the formula
