If the load is 50 N, what effort force is required? A3: 50 N (MA = 1 → Effort = Load/1 = 50 N)
To raise the load 1 meter, how far must you pull the rope? A3: 2 meters (distance doubles) student exploration pulley lab answer key
Does a fixed pulley reduce the force needed? A2: No. It changes the direction of force, not the magnitude. If the load is 50 N, what effort force is required
Load = 200 N. Effort force? A2: 50 N (200 ÷ 4 = 50) If the load is 50 N
Why is actual MA always less than ideal MA? A: Friction in the pulleys and rope stiffness reduce efficiency.
If the load is 100 N, what effort force is required? A2: 50 N (MA = 2 → Effort = 100 N / 2)
