The Ultimate Bowling Guide
In the otherwise flat surface of the bed. If a marble is now placed near the baseball, it will roll along the curved surface into the depression. The bending of its environment made by the baseball therefore creates an attraction between the baseball and the marble. Now suppose we replace the baseball with a bowling ball. It will make a bigger depression and the marble will roll in further and be moving faster as it hits the bottom. We therefore infer from the analogy that the strength of the attraction between the bodies depends on the amount by which the surface is curved. Gravity also behaves this way, according to the general theory of relativity. According to that theory, mass creates a curvature of space, and gravitational motion occurs as bodies move along the curvature.11
Object, whose mass is not evenly distributed, to twist around so that the more massive end points towards the body it is orbiting. For example, if a bowling pin were to orbit the Earth, after time, the base would point towards the Earth, and the top would be pointing away from the Earth. As the Moon is in orbit around the Earth, the parts of the Moon closest to the Earth receive a slightly stronger gravitational attraction than those parts further away. Although the Moon looks round and symmetrical, the mass within it is actually unevenly spread and the side we see from the Earth contains more mass than the side we cannot see. It is the gravity gradient that keeps one face of the Moon always pointed towards the Earth, and the far side always pointed away. This is also known as tidal locking. A gravity gradient also causes the tides. The Moon does not orbit the centre of the Earth, but rather the centre of mass of the Earth-Moon system, called the barycentre. This is located about...
Figure 8-4 summarizes satellite decay in a convenient manner for mission analysis use. The 3 sets of curves show lifetime as a function of initial circular altitude for satellites with ballistic coefficients that are low (20 kg m2), moderate (65 kg m2), and high (200 kg m2). The spread in the curves near the middle represents the difference between solar maximum (F10.7 225) and solar minimum (F10.7 75). At the left of the figure, below about 200 km, satellite orbits decay within a few days, the atmospheric density is largely independent of the solar cycle (see Fig. 8-11), and the upper and lower curves for each coefficient begin to merge. From there to lifetimes of about half a solar cycle (approximately 5 years) there will be a very strong difference between satellites launched at the start of solar minimum (upper curve) and those launched at the start of solar maximum (lower curve). Also note that the difference between the solar maximum and solar minimum curves is larger for...
One way to imagine space in Einstein's view is as a vast rubber sheet with a heavy bowling ball creating a big dimple in it. The mass of the bowling ball distorts the sheet, which is a two-dimensional representation of space. In this model, a massive object distorts space itself. Imagine that instead of making a dimple in the sheet (as the bowling ball does), an object were to make an infinitely deep sinkhole. That region of space would be a black hole.
''We noticed the same thing on Apollo 8. It's very similar to looking at a light shining on something like a billiard ball or a bowling ball you get this bright spot in the blue of the water, and that turns it to sort of a greyish colour.'' The technical term for this phenomenon was specular reflection.
Can cause considerable structural damage. For example, a small 0.3-centimeter-diameter sphere of aluminum that is traveling at 10 kilometers per second contains about the same amount of kinetic energy as a large bowling ball traveling at 100 kilometers per hour. Impact with such an object would do severe damage to a spacecraft or space vehicle.
