R is the radius of the object. There is a negative sign in front of the equation because objects in free fall always fall downwards toward the center of the object. The acceleration due to gravity is <span>1.62 m/s2</span><span>. This is approximately 1/6 that of the acceleration due to gravity on Earth, </span><span>9.81 m/s2</span><span>.</span>
The numbers written in scientific notations have some rules to follow.
If the scientific values are expressed in exponential powers of 10, the integer value should be between 1 and 9. The respective powers will be added to the exponential order.
The scientific notation is the convenient form of expressing the scientific values that could be easily used in the calculations.
The digits after the decimal point are used according to the resolution of the scientific values.
