Dynamics - Advanced

The Not-so-simple Pendulum 1

Age 16 to 18
Challenge Level Yellow starYellow star

See how the motion of the simple pendulum is not-so-simple after all.

Little Little G

Age 16 to 18
Challenge Level Yellow starYellow star

See how little g and your weight varies around the world. Did this variation help Bob Beamon to long-jumping succes in 1968?

Falling Beads
