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 -11 N·m 2 /kg 2 ). 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 ten-millionth 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.
