Physical Science Review
... Electric field is affected by distance. The farther away the charge, the less force. In electric field, the opposite charges attract. Like charges repel Magnetic field is affected by distance. The farther away a magnet, the less force. In magnetic field, the opposite poles attract. Like pole ...

CHAPTER 2: Special Theory of Relativity
... This hypothesis suggested that the Earth somehow “dragged” the ether along as it rotates on its axis and revolves about the sun. Earth would then be the only place in the universe where Maxwell’s equations would be valid without further modifications (correction factors) ...

... have to be 500 km/sec. Thus, it is imaginable that there is a massive body for which the escape velocity equals the speed of light: 300000 km/sec. Such an object is called a ‘black hole’. Presumably light from such an object could not escape to be seen by a distant observer, so that it would not app ...

JKDoranPaper - FSU High Energy Physics
... The theory of special relativity makes two postulates (Prosper, Krane). The first is that the laws of physics are the same for all non-accelerating observers, or observers moving in an inertial frame of reference. This means that it is impossible to verify whether you or your surroundings are moving ...

Chapter 10 The Deaths of Stars
... • The length of an object (as observed from “rest”) decreases in the direction of its motion as its speed increases. Length contraction • Clocks that you see as moving run more slowly than do clocks at rest. Biological processes slow down. Time dilation • Space and time cannot be considered as two s ...

Gravitation
... Is there any evidence that Newton’s theory of universal gravitation is true? The word ‘true’ is not appropriate for scientific theories: We understand observations of the universe around us in terms of our theories. If there are carefully observed events that cannot be explained by our theory, then ...
