Description
A string wrapped around the hub of a spool is pulled at various angles, causing the spool to go forward, backward, or skid depending on the direction of the pull. This demonstration illustrates the principles of friction and torque, showing how the angle of the applied force influences the direction of motion. It provides a clear visual example of how forces interact with rotational motion and frictional forces at the point of contact.
