6
Systems with a stable equilibrium point often exhibit Oscillations B is a stable equilibrium point because 1)When the ball is pushed to the right from B the force of gravity acts to pull it back to B 2)And when the ball is pushed to the left from B the force of gravity acts to pull it back to B

7
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.

8
The frequency of an Oscillating system is the number of cycle per second and is just 1/Period The frequency unit of cycles per sec (1/s) has the special name Hertz (Hz)

9
The frequency of an Oscillating system is the number of cycle per second The frequency unit of cycles per sec (1/s) has the special name Hertz (Hz) What is the frequency of vibration for a humming birds wings that has a period of 0.02 second?

The frequency of an Oscillating system is the number of cycle per second The frequency unit of cycles per sec (1/s) has the special name Hertz (Hz) What is the frequency of vibration for a humming birds wings that has a period of 0.02 second?

11
Since the frequency of an Oscillating system is the number of cycle per second, the period (number of seconds per cycle) is: A seismic signal has a frequency of 0.2 Hz. What is the period of this signal?
