Atwood Machine

LEFT side is HEAVIER

NOTE the simulation reverses the positions of m1 and m2. Make the simulation values match our document.

Launch the simulation below.

• Adjust the angle to 90 degrees
• Check the box to show Free-Body Diagram

Run the simulation.

Review the elevator document linked below

Return to the Atwood Simulation.

Check the box to show Numerical Values then run the Atwood Simulation.

Define the direction of EACH mass' acceleration as POSITIVE.

So one mass will have the positive direction pointing up and one mass will have positive direction pointing down.

System of Equations - You're welcomed to have your teacher check your summation of forces for each mass before solving for the acceleration.
