Physics 312: Junior Seminar
A guide to basic information resources on Junior Seminar, Physics 312.
Change in the velocity of a body with respect to time. Since velocity is a vector quantity, involving both magnitude and direction, acceleration is also a vector. In order to produce an acceleration, a force must be applied to the body.
Branch of science traditionally defined as the study of matter, energy, and the relation between them; it was called natural philosophy until the late 19th cent. and is still known by this name at a few universities.
From Collins Dictionary of Astronomy Symbol: vr. The velocity of a star along the line of sight of an observer. It is calculated directly from the doppler shift (see Doppler effect) in the lines of the star's spectrum: if the star is receding there will be a redshift in its spectral lines and the radial velocity will be positive; an approaching star will produce a blueshift and the velocity will be negative.
Physical principle, enunciated by Werner Heisenberg in 1927, that places an absolute, theoretical limit on the combined accuracy of certain pairs of simultaneous, related measurements. The accuracy of a measurement is given by the uncertainty in the result; if the measurement is exact, the uncertainty is zero.
From The Penguin Dictionary of Mathematics Symbol: v. The rate of change of position with time when the direction of motion is specified. Velocity v is thus a vector quantity; its magnitude v is referred to as speed.
Draws together all aspects of energy, covering a wealth of areas throughout the natural, social and engineering sciences, providing easily accessible information about all aspects of energy, written by leading international authorities.
This comprehensive Encyclopedia covers the full history of astronomy from its ancient origins in Africa, South America, the Middle East and China to the latest developments in astrophysics and space-based research.
"This intriguing 6-part PBS documentary series explores the concepts of physics from familiar theories, such as Newton's Law of Gravity, to the latest in scientific research, like string theory and M-theory. By connecting all of this research with the medium of light, we can gain a deeper understanding not only of our immediate reality, but of the unseen realities that are hidden beyond our perception. Starting with Einstein's Theory of Relativity, Physics of Light explores the true nature of light, peers inside the atom, and looks ahead to the most cutting edge theories in physics."
"In the 24 lectures of The Science of Energy: Resources and Power Explained, award-winning professor and expert geophysicist Michael E. Wysession of Washington University in St. Louis presents an unbiased investigation into the energy sources that power our world. Vividly illustrated with animations, 3-D graphics, graphs, in-studio demonstrations, and other visuals that make scientific and mathematical concepts approachable and understandable, The Science of Energy is a marvelous window into the inner workings of energy that will keep you constantly engaged."
"This engrossing series takes a spectacular journey into the world of sound—and reveals what the physics of sound can tell us about the world and how it works. Scientist Helen Czerski uncovers the miasma of mathematical waveforms that combine to create each sound. She explores the secrets that sound can unlock, from the structure of the universe to the way that animals communicate over thousands of miles. Packed with spectacular imagery, jaw-dropping experiments and some of the most remarkable sounds in the world, this is the ultimate guide to one of the universe’s most magical phenomena."
