A central discovery in the lab is the trade-off between force and distance. To lift a heavy object with less force, the user must pull a longer length of rope.
Try changing the load mass or adding more pulleys. Does the effort force scale proportionally?
By conducting this lab, students will gain hands-on experience with pulleys and develop a solid understanding of their mechanical advantage, preparing them for more advanced topics in physics and engineering.
). You’ll notice that despite the different pulley setups, the total work required to lift the load to a certain height remains constant (ignoring friction). Summary for Students
