Monkey See … Monkey Do!
Gotcha!
Antisymmetric Tracks … and the winner is?
Symmetry-breaking in Classical Physics
Atwood’s Machine
• Measure gravity by “slowing it down”
• Measured by hanging two slightly different masses and reading the acceleration
Atwood’s Machine
• Smartphone is placed in a plastic bag
• App measures the acceleration
• Data compared to theory
• 99% accurate
Acceleration App
• Today is your lucky day!
• Everybody in the audience gets it FREE!
Centripetal Acceleration Lab
• The phone is placed on a turntable and the app is run
• a = mv2 /r
