Systems with a stable equilibrium point often exhibit Oscillations
B is a stable equilibrium point because1)When the ball is pushed to the right from B the force of gravity acts to pull it back to B2)And when the ball is pushed to the left from B the force of gravity acts to pull it back to B

The Period of an Oscillating system is the time it takes to complete one full cycle
The period is the time it takes to go from A over to C and back to A.

Since the frequency of an Oscillating system is the number of cycle per second, the period
(number of seconds per cycle) is:
frequency
1Period
