Question

A pendulum ocsillates 60 times in 6 seconds. What will be its frequency?

Answer 1

Frequency=60/6=10Hz

Time Pedriod=1/f=1/10

By dampening. This can be done by changing the length of the pendulum . The period is 2*pi*square root of (L/g), where L is the length of the pendulum and g the acceleration due to gravity. A pendulum clock can be made faster by turning the adjustment screw on the bottom of the bob inward, making the pendulum slightly shorter.
