The acceleration due to gravity on Uranus is 10.72, while the acceleration due to gravity of Earth is 9.8 m/s2 (or 9.81, it depends on who you ask. 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. Its SI unit exists m/s2. And of course, knowing just how strong it is on other planets will be essential to manned missions (and perhaps even settlement) there. Get access to this video and our entire Q&A library, Calculating Acceleration Due to Gravity: Formula & Concept. Weight. Earth is also unique in phrases of monikers.
