The acceleration due to gravity, denoted by the symbol g, is the acceleration of a body caused by the force acting on the body due to the earth’s gravitational field.This force can be written as mg, where m is the mass of the body.Since g is the force on unit mass, then it also represents the strength of the gravitational field at the point where the measurement is made. d. instantaneous acceleration. Acceleration due to gravity (g) is i. Thus, the value of gravity is maximum at the Earth's surface and decreases with increase in height as well as with depth. The acceleration due to gravity at the surface of a planet, or outside it, depends only on the mass of the planet, and the distance of the point from the center of the planet. Near the surface of Earth, the acceleration due to gravity is approximately constant. However, the actual acceleration of a body in free fall varies with location. If the mass of this portion is denoted by M', the acceleration due to gravity at the point by g' h and the density of the Earth by , then (G.8) Now, acceleration due to gravity at the surface can be written as (G.9) Dividing equation (G.8) by equation (G.9), we obtain (G.10) The value of gravitational acceleration decreases if one moves towards the center of the Earth, e.g., in mines. Its SI unit is ms². Length of a Simple Pendulum It is the name for the general phenomenon that stuff falls down. Abstract.
