Student Exploration Pulley Lab Answer Key !!link!! -

To raise the load 1 meter, how far must you pull the rope? A3: 2 meters (distance doubles)

To lift load 0.5 m, how much rope do you pull? A3: 2.0 m (0.5 × MA)

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. student exploration pulley lab answer key

Why is actual MA always less than ideal MA? A: Friction in the pulleys and rope stiffness reduce efficiency.

Load = 200 N. Effort force? A2: 50 N (200 ÷ 4 = 50) To raise the load 1 meter, how far must you pull the rope

If the load is 100 N, what effort force is required? A2: 50 N (MA = 2 → Effort = 100 N / 2)

Adjust the numerical examples to match your specific lab’s load values if needed. Load = 200 N

If the load is 50 N, what effort force is required? A3: 50 N (MA = 1 → Effort = Load/1 = 50 N)
