Master the science of balance on a seesaw lever. Place different weights on numbered pegs, compare turning effects, and discover the rule that keeps the beam perfectly balanced.

🎮 Try It
• Drag masses onto the beam pegs and remove the support stands to see which side tilts down.
• Check Position markers and Mass labels to clearly see distances and weights on both sides.
• Place a heavy object near the center and test whether a lighter object placed further out can balance it.

🎯 Your Mission
In Balance Lab, place a 20 kg object 1.00 m from the pivot and balance it with a 10 kg object on the opposite side.
