Gravity is based on an object's mass and your distance from the center. When you're on the surface of a planet, you can use the planet's radius to calculate your distance from the center. If you compare the mass of the moon to the earth's, you will find that the moon's mass is...
Planets orbit their parent stars while separated by enormous distances – in our solar system, planets are likegrains of sandin a region the size of a football field. The time that planets take to orbit their suns have no specific relationship to each other. But sometimes, their orbi...
In his experiments with gravity, Isaac Newton showed how the motion of each planet in the solar system results from the combined gravitational pull of the Sun and of all the other planets, each contributing according to their mass and distance from the o
To calculate the ratio between Earth's surface gravity and that of any other celestial body, you must compute them separately using the formula above, and then divide the desired planet's gravitational force by Earth's. We will spare you the work: Mercury: 0.38 Venus: 0.91 Earth: 1.00 ...

To calculate the weight of sand, you need to determine the volume of each mineral in the sand, multiply the volume by the mass density. Then you can multiply the masses of each component mineral by the local acceleration of gravity, to determine the weight of the sand. ...

Our curved Earth also aligns perfectly with all of physics. Additionally, all of the other planets ever discovered also appear round, because that's how gravity likes things. If you use gravity to, say, trust yourGPSto give you accurate positions and calculate trajectories, then that same forc...
