Student Exploration Pulley Lab Answer Key [ORIGINAL]

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

Use this answer key to check your work, but more importantly, understand why the numbers appear as they do. Physics isn’t just about getting the right answer—it’s about predicting the trade-offs.

Why is actual MA always less than ideal MA? A: Friction in the pulleys and rope stiffness reduce efficiency. student exploration pulley lab answer key

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

Load = 200 N. Effort force? A2: 50 N (200 ÷ 4 = 50) If the load is 50 N, what effort force is required

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

To lift load 0.5 m, how much rope do you pull? A3: 2.0 m (0.5 × MA) Why is actual MA always less than ideal MA

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