... A cannon weighing 1 ton (metric ton, 1000 kilograms) fires a 10 kg shell at 1000 meters/second. With what velocity does the cannon recoil? ... The quantity "mass times velocity" (or "the product of mass and velocity") is called momentum (plural: momenta) and is often denoted by the letter P. One way of interpreting the last equation (5) is to state that the momentum given to the cannon equals the momentum given to the shell. ... v 1 = 1000 m/s P 1 = m 1 v 1 = 10 kg x 1000 m/s = 10,000 kg-m/s . ...

The inner radiation belt, discovered by Explorers 1 and 3, owes its existence to the extraordinary stability of trapped orbits near the Earth. ... If these are electrically charged, e.g. electrons or ions, they will often end up trapped by the Earth's magnetic field. ... The energetic protons which then materialize are grabbed by the Earth's magnetic field, often on trapped orbits which do not return to the atmosphere, in which the proton can stay trapped for a rather long time. ...
