"Because of its low gravity, it takes 22 times less energy to send a pound of stuff from the moon into orbit around the Earth than to lift it up from Earth," said Gregg Maryniak, executive director of the X-Prize Foundation, whash has created a $10 million award for the first company to develop a way to launch people and goods into space more inexpensively and frequently.
If a cloud begins to contract because of its own gravity, its interior heats up as gravitational energy is converted to heat energy, reaching millions of degrees, and nuclear reactions begin that change one element into another, releasing energy.
Jupiter has been called the Solar System's vacuum cleaner, because of its immense gravity well and location near the inner Solar System.
Magnetite is widely used in most dense-medium processes in the coal industry because of its higher specific gravity, stability in suspension, lower viscosity, and easy availability, recovery and reuse.
Imagine that the universe started with some region of false vacuum, which (because of its repulsive force of gravity) expanded exponentially until some part of it decayed to produce a "pocket universe" like our own.
Unlike the Roadster, which carried its batteries at the front of the car, the Model S had its underneath the floor, which gave extra storage space in front and improved handling because of its low centre of gravity.
Because of its high center of gravity and serious entanglement, the millet stem was hard to be divided in the mechanized harvesting.
Because of its masconian character, the gravity field of the Moon requires higher order truncations to give a realistic description of the long-term behavior of low-lunar orbits.
The ejecta excavated by impacts is deposited differently on Ida than on planets because of its rapid rotation, low gravity and irregular shape.
