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
