acceleration due to gravity refers to the constant value of 9.81 meter per second ^2 or 32.174 feet per second ^2.
These values are used in physics with Newton's Second Law, which
equates the relationship of a force to the product of mass and
acceleration.
While any object can be accelerated
through applied forces, a free falling object within the earth's
gravitational field is subject to this acceleration constant, assuming
that friction is negligible. This value is also used for the scientific
definition of weight, where it is equal to the product of the
gravitational constant and mass. This explains why weights vary in
environments with different gravitational fields
When any object is moved then its speed is changed which is called velocity while the change in velocity is acceleration. When it is changed continues then it is in accelerating condition which is called the rate of acceleration.
It is equal to the ratio of change in velocity with respect to time
between the given paths. The vector quantity acceleration is used to
show the increasing or decreasing speed or changing direction of object.
As we know that a free falling object is under the influence of
gravity with an acceleration of 9.8 m/s in downward direction. The free
falling objects are free from air resistance. This is the gravitational
acceleration or acceleration under gravity denoted with the symbol of g
with the standard value of 9.8 m/s but it is varied in different
gravitational environments. Gravitational Fields widget is used for
investigating the effect of location on the value of g. Let’s discuss
about the calculation of acceleration due to gravitational force and its
properties
