... We use the concept of mass to describe how much matter is inside a physical object. Anything that takes up space has matter in it. Generally, the bigger an object is, the more mass it has, but not always. If you could blow up a balloon to be the same size as an elephant, the balloon would still have ...

Newton`s 1st Law of Motion
... therefore comes back to the table very nicely because it and the table have had the same fixed horizontal speed. (Why doesn't it maintain its upwards motion? Answer: because the force of gravity on the ball is an external force!) Whether the train is at rest or moving as described, it will be an ine ...

Kepler`s Laws
... Johannes Kepler (1571–1630) discovered three laws of planetary motion in the early seventeenth century. These laws were discovered empirically, after studying for many years data collected primarily by the Danish astronomer Tycho Brahe (1546–1601). The first mathematical derivation of Kepler’s laws a ...
