What is Acceleration due to Gravity? This value, however, assumes that material of zero density occupies the whole space between the point of observation and sea level, and it is therefore termed the free-air correction factor. Acceleration due to gravity ‘g’ by Bar Pendulum OBJECT: To determine the value of acceleration due to gravity and radius of gyration using bar pendulum. On the earth surface, g is inversely proportional to the radius of the earth. I have seen in a reference book that the value of the acceleration due to gravity is always -9.8m/s^2, whether the body is falling downwards or it goes upwards because the gravitational force is acting only in the downward direction i.e. Calculation of the value of acceleration due to gravity .
