The rate of mass flow per unit area. The common symbols are j, J, φ, or Φ, sometimes with subscript m to indicate mass is the flowing quantity. Its SI units are kg s−1 m−2. mass moment of inertia A property of a distribution of mass in space that measures its resistance to rotational acceleration about an axis. mass number
[1] [2] [3] Astronauts in orbit have the sensation of being weightless because they are in free fall around the Earth, [4] not because they are so far away from the Earth that its gravitational pull is negligible. For example, on the International Space Station the Earth's gravity is nearly 90% as strong as at the surface. Objects orbiting in ...

Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
where k e is the Coulomb constant (k e ≈ 9 × 10 9 N⋅m 2 ⋅C −2), q 1 and q 2 are the signed magnitudes of the charges, and the scalar r is the distance between the charges. The force of the interaction between the charges is attractive if the charges have opposite signs (i.e., F is negative) and repulsive if like-signed (i.e., F is ...
