Acceleration due to gravity is 9.8m/s/s

According
to Galileo, all falling objects accelerate at the same rate. At a given
location on the earth and in the absence of air resistance, all objects fall
with the same uniform acceleration. Thus, two objects of different mass,
dropped from the same height, will hit the ground at the same time. |

160 F = g 160 M A falling bowling ball has 160 times
the gravitational force acting on it as compared to a golf ball. The weight
force is greater. The bowling ball falls with an
acceleration of 9.8m/s2 because its inertia (mass) is 160 times
greater than a golf ball. It resists the greater pull of gravity. |
1 F = g 1M The force pulling down on a golf ball is much less
as compared to a bowling ball. The weight is less. The small force acting on this small ball with very little inertia also results in the same acceleration due to gravity or, 9.8m/s2. |
