A simple pendulum is one in which all of the mass is concentrated in a point at the end of a massless cord. Let's plot a few solutions on the vector field. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. This means that for any dis placement angle 0 the same restoring torque acts on both the rod and the simple pendulum. In the equilibrium position O,the net force on the bob is zero and the bob is stationary. In the example of a kid being pushed in the swings at a playground, this is the time it takes the kid to be pushed and then return back for another push. 2 Theory 2. A simple pendulum mean a Bob is attached to a rigid point by a weight less thread and when a force applied to it ,it moves to its extreme position and slows down and came into rest and back to its maen position. it is maximum when the mass at the bottom and slows down when the mass swings up. htm" I wanted to set up a pendulum with a small magnet on its end, place an electromagnet beneath where the pendulum would swing, and then energize the electromagnet briefly from time to time to "nudge" the pendulum so that it would swing "forever". The pendulum has been used since the 16th century to measure time. Sometimes the conclusion may be required to go after the discussion, in which case it will not be a summary of the results but will be what you conclude based on your discussion. squareroot(L/g) where L is the length of the string and g is the acceleration due to gravity.

We will then compare this value with the commonly accepted value of 9. BTW major physics spoiler: the mass doesn't affect the period of the pendulum (ignoring air resistance) so if you're planning on using it as an independent variable, you're not going to have much to talk about. " It is sometimes convenient to specify the location of the axis of suspension S by its distance s from one end of the bar, instead of by its distance h from the center of gravity G. How is this conserved then? Since M and L are constants, but omega changes. Such oscillatory motion is called simple harmonic motion. The lowest velocity, always zero, coincides with the pendulum's farthest distance from the center of the earth. The pendulum was measured from the top support point down towards the middle of the metal weight on the string using a meter stick.
