In this display we will deal with spinning motion about an axis fixed at the origin of our reference frame. The object is a disk whose radius is 0.5m and mass is 5kg. The center of mass of the disk is on the axis of rotation. By clicking the mouse button and dragging the mouse, you establish a force vector attached to the disk at the point on which you clicked and oriented in a fixed direction relative to the disk. A click on the Action button will release the disk to respond to the applied force. When you cut the action, the values of torque, angular acceleration, angular velocity and angular position are displayed.
