Student Exploration Pulley Lab Answer Key File

In the lab, why does the load sometimes not rise even when you pull? A: The effort force is less than the load’s weight (if MA<1), or friction is too high.

Fixed pulley = directional advantage only. student exploration pulley lab answer key

If you’ve just finished the “Student Exploration: Pulley Lab” simulation (common in Gizmos, ExploreLearning, or similar platforms), you know it’s not just about pulling ropes. It’s about mechanical advantage, effort force, and trade-offs. In the lab, why does the load sometimes

Reality: Friction eventually limits gains. Very high MA systems feel “sticky.” In the lab
