... only if no net torque acts on the system. This isn’t the case for either the pulley or the disk: A net torque due to the tension force acts on the pulley as it rotates, and a net torque due to the force of friction acts on the disk as it rolls downhill. For both objects the moment of inertia I remai ...

... The scale will read more than 600 N. In general, the scale reads the downward force (N) exerted on it from the object placed on it, in this case, the student. If the student is not accelerating then the upward force on the student IS equal in magnitude to the student’s weight. In reaction to that th ...
