Gravitational Potential Energy to Kinetic Energy - Pendulum.
You can often see a pendulum swinging beneath a clock.
The time it takes for the pendulum to swing
back and forth
is used to make the clock keep the
correct time.
During the pendulum's swing,
GPE is transferred into KE which is transferred
back into GPE and so
on.
At stage
1 the pendulum has maximum GPE and zero
KE.
At stage 2 the pendulum has minimum
GPE and
maximum KE.
At stage 3 the pendulum has maximum
GPE and
zero KE.
At stages 1 and
3, the pendulum is stationary.
At stage 2, the pendulum has
its fastest speed.
