A light pulley is a type of pulley that has negligible mass and friction, meaning it does not add any significant weight or resistance to the system it is used in.
Imagine a smooth, lightweight skateboard wheel. Just like how the skateboard wheel spins freely without adding much weight or slowing down the skateboard, a light pulley rotates smoothly without affecting the overall motion of the system.
Tension: The force transmitted through a string, rope, or cable when it is pulled tight. It acts in opposite directions on each end of the string.
Mechanical Advantage: The ratio of output force to input force in a simple machine. In the case of a light pulley, it can increase mechanical advantage by changing the direction of applied force.
Torque: The rotational equivalent of force. In relation to a light pulley, torque refers to the turning effect produced by an applied force around its axis.
