5. Practice: Each mass is pulling the rope in the opposite direction with a force equal to its weight. Therefore, the net force is equal to the weight difference between mass A and mass B. For each combination of masses, calculate the total mass, net force, and acceleration. Next, measure the final velocity, time, and acceleration for each combination using the Gizmo. Include all units. Mass A Mass B Total mass Net force Calculated Final acceleration velocity Time Measured acceleration 1.0 kg 2.5 kg 4.0 kg 1.0 kg 3.0 kg 3.5 kg 5.0 kg 5.0 kg
6. Analyze: How well did your calculated values for acceleration match up with the measured values ? What are the possible sources of error?
