... Newton's Laws . ... If object A exerts a force F on object B, . then object B exerts an equal and opposite force ?F on object A" . ... There exists a whole set of situations where two equal and opposite forces act on the same object, canceling each other so that no acceleration (or even no motion) occurs. ... It is all in Newton's third law: as your legs propel your body towards the dock, they also apply to the boat an equal force in the opposite direction, which pushes it away from the dock. ...

Isaac Newton on the British pound note . ... 1) In the absence of forces, a body at rest will stay at rest, and a body moving at a constant velocity in a straight line continues doing so indefinitely. 2) When a force is applied to an object ("body"), it accelerates in the direction of the force. ... The second law gives an explicit formula, and hence is the one most useful. ... Mach argued that Newton's laws boil down to one law: . ... Mass and force are now readily derived. ...

... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

Fit the ring around the equator and then change its inclination from 0 degrees (equatorial orbit used by geosynchronous satellites) to 28.5 degrees (space shuttle orbit) to 51.6 degrees (space station orbit) to 90 degrees (polar orbit used by spy satellites). by Rob Landis, Space Telescope Science Institute . ...

... However to my eye the colour scheme that looks best is what might be described as a `thermal' one, ie one in which cool objects (objects with a long-wavelength excess) are coloured red and hot objects blue, with the intermediate sequence going from red through yellow and white to blue. ... The parameter heat shifts colours along the thermal sequence: at heat = -1 all colours go to red, at +1 they are all blue, with again 0 having no effect. ...

Appendix A: Derivation of the Secondary Sag as a Function of Telescope Altitude . One-half of the secondary support structure consists of the two rods shown in Figure 9 plus the opposing rods on the other side of the secondary cage. The total tension force on a single rod can be decomposed into a thermal component and a base tension that is set at the time when the rods are originally tensioned with the turnbuckles. ... The axial force balance equation is then given by . ...

Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ...
