In this final poster we will study the relationship between the gravitational force on Swift and its acceleration and veloc-ity. Recall that as Swift enters its orbit, it has velocity that is purely “horizontal” …

Gravity is a physical force of attraction between objects. Objects with a small mass have a weak gravitational force while those with a large mass have a strong force. You are held down to the …

Using gravity potentials, one can easily prove that the gravitational acceleration of a spheri-cally symmetric mass distribution, at a point outside the mass, is the same as the acceleration obtained by …

It holds “gravitational force” and “the fictitious force which arises from acceleration relative to the local inertial frame(s)”—in short: it holds gravitation and non-inertiality—to be physically indistinguishable; …

Analyzing gravitational forces at work can provide an endless supply of information to astronomers. But in order to interpret distant phenomena by applying the laws of gravity, astronomers must assume …

From the earliest times, gravity meant the tendency of most bodies to fall to earth. In contrast, things that leaped upwards, like flames of fire, were said to have “levity”.

• Similarly for a sphere of matter. • Like the case of a ring, a particle inside a spherical shell of matter feels zero gravitational force from the shell. Gravity: Force on a mass m on Earth's surface: Fg= …
