When the bob of the pendulum is released after taking it slightly to one side, it:
becomes still and does not move
comes to rest at the mean position
begins to move to and fro
begins to move up and down.
When the bob of the pendulum is released after taking it slightly to one side, it begins to move to and fro.
It takes 0.2 s for a pendulum bob to move from mean position to one end. What is the time period of pendulum ?
Consider that the bob of a simple pendulum has moved from its mean position to one of its extreme positions and then again to mean position from where it moved to the other extreme position and then back to the mean position. The bob of the simple pendulum has now completed:
A simple pendulum is arranged using a small metallic bob of mass 'm'and a light rubber cord of length 'L' (on suspending the bob), area of cross section 'A' and Young's modulus 'Y'. [One should use inextensible cord only for simple pendulum!]. When this unconventional pendulum is at rest in its mean position, the bob is pulled slightly down and is released. Then, the period of the vertical oscillation of the bob is (assuming that the size of the bob is negligible compared to the length of the cord):
