Atwood machine
Connect two hanging masses over a pulley and predict which side descends.
What to notice
The tension is the same on both sides of an ideal pulley. Equal masses balance.
Key relation
a = (m₂ − m₁)g/(m₁ + m₂)
Try this
Make the masses equal, then increase only the right-hand mass.
What you can change
- Left mass m₁: 1 to 8 kg
- Right mass m₂: 1 to 8 kg
