The formula is: where Thus, the value of g on the Earth is g=9.8m/s 2. Mass of the Earth is 6 10 24 kg. This force causes all free-falling objects on Earth to have a unique acceleration value of approximately 9.8 m/s/s, directed downward. Newton's law of universal gravitation states that there is a gravitational force between any two masses that is equal in magnitude for each mass, and is aligned to draw the two masses toward each other. [Latex: v=sqrt{2gd}], What has been the average velocity of an object that has been falling for t seconds? A ball is dropped from Uranus from a height of 6.2 meters. m You mean acceleration due to gravity. Another way to look at it is that objects dropped towards Uranus will accelerate towards the planet at 8.69 m/s2. We also see that, although force is depending on the mass of the object, F=Gr2Mm But acceleration due to gravity is independent of the mass.
