Experiment No. 07
Acceleration due to Gravity:
The acceleration that an object experiences because of gravity when it falls freely close to the surface of a
massive body, such as a planet. Also known as the acceleration of free fall, its value can be calculated
from the formula.
=
( + )
g GM R h 2
where M is the mass of the gravitating body (such as the Earth), R is the radius of the body, h is the height
above the surface, and G is the gravitational constant ( 6.6742 × 10

).
Compound Pendulum:
A rigid body with distributed mass able to freely pivot about a horizontal axis 'P' which does not coincide
with the center of gravity is called a compound pendulum.
Meter:
The metre (or meter), symbol m, is the base unit of length in the International System of Units (SI).
Originally intended to be one tenmillionth of the distance from the Earth's equator to the North Pole (at
sea level), its definition has been periodically refined to reflect growing knowledge of metrology.
