Newton’s Second Law for Rotation Lab What factors would affect the angular acceleration? Torque Something about the mass Purpose: To create graphical and mathematical representations of the relationship between the torque and the angular acceleration for a system with constant mass. Angular Acceleration

Newton’s Second Law for Rotation Lab The clamp-on Super Pulley must be adjusted at an angle, so that the thread runs in a line tangent to the point where it leaves the 3-step Pulley and straight down the middle of the groove on the clamp-on Super Pulley (Figure 1.2).

Newton’s Second Law for Rotation Lab Since the masses are accelerating downward. Since the string doesn’t slip, the linear acceleration of the masses is equal to the tangential acceleration of the outside of the pulley.
