A simple pendulum consists of a bob suspended from a wire or string with negligible mass, with the length defined as the distance between the point of suspension and the center of the bob. The pendulum oscillates in a to-and-fro motion about a fixed point, with the equilibrium position being where the pendulum is at rest, and the amplitude being the maximum displacement of the bob from the equilibrium position.

3. A simple pendulum is defined as an
object that has a small mass, also
known as the pendulum bob, which
is suspended from a wire or string of
negligible mass.

5. The length of a simple pendulum is the
distance between the point at which it
is hung from the stand and the centre
of the bob.

6. Oscillation is the to and fro motion of
the pendulum about a fixed point.

7. When the pendulum is at rest, it is said
to be in equilibrium.

8. The maximum displacement of the bob
from the equilibrium position is its
amplitude.
AMPLITUDE=AB 0R BC

9. The time taken for one oscillation is the
period.
Period =Time taken for a definite number
of oscillations/Number of oscillations
T =t/n

10. Frequency is the number of oscillations per
second.
F =n/t
