One-dimensional motion is motion along a straight line, and cen be represented by four variables, velocity (v), time (t), displacement (x), and acceleration (a).  There are five equations that can solve for any unknown variable, assuming constant acceleration:\ndelta x=v(delta t)\ndelta v=a(delta t)\ndelta x=v initial*delta t + 0.5a(delta t)^2\ndelta x=v(delta t) - .5a(delta t)^2\nv^2=v inital^2 + 2a(delta x)\n\nAlso, keep in mind the derivative of displacement is velocity and the derivative of velocity is acceleration.  Likewise, the integral of acceleration is velocity and the integral of velocity is displacement.

Did you put your entire homework assignment on here? I noticed you posted a bunch of science questions just now.\nIf you don't have your textbook handy [you really should be looking up these answers so that you can remember and understand them when you have your test/exam], go to the links below and look them up. The 1st is a down loadable physics textbook. The 2nd has animations of physics.

Someone posted the exact same set of questions a few days back, either here or on the physics page - you ought to be able to find the methods in the responses. Have a look.\n\n\nBest of Luck - Mike

Well\nrelativity \n\nPhysical theory, introduced by Albert Einstein, that discards the concept of absolute motion and instead treats only relative motion between two systems or frames of reference. One consequence of the theory is that space and time are no longer viewed as separate, independent entities but rather are seen to form a four-dimensional continuum called space-time. Full comprehension of the mathematical formulation of the theory can be attained only through a study of certain branches of mathematics, e.g., tensor calculus. Both the special and general theories have been established and accepted into the structure of physics. Einstein also sought unsuccessfully for many years to incorporate the theory into a unified field theory valid also for subatomic and electromagnetic phenomena.\n\nEvolution from Classical Theory\n\nThe modern theory is an extension of the simpler Galilean or Newtonian concept of relativity, which holds that the laws of mechanics are the same in one system as in another system in uniform motion relative to it. Thus, it is impossible to detect the motion of a system by measurements made within the system, and such motion can be observed only in relation to other systems in uniform motion. The older concept of relativity assumes that space and time are correctly measured separately and regards them as absolute and independent realities. The system of relativity and mechanics of Galileo and Newton is perfectly self-consistent, but the addition of Maxwell's theory of electricity and magnetism to the system leads to fundamental theoretical difficulties related to the problem of absolute motion.

The only way to prove this formula is to conduct an experiment. For the theory, recall that current density j is the fundamental quantity in Ohm's law. Also you will require the Boltzmann energy distribution.

Good question. There really is no good answer except to say that the basic equations of physics have a lot of symmetry. To get that symmetry requires there to be only a handfull of truly elementary particles. The Big Bang has nothing to do with this. It wasn't an explosion in the conventional sense and didn't 'break up' matter into the fundamental particles. It's more like the fundamental particles 'condensed' out of the vacuum.

Giancoli covers it pretty well.  I don't know how deep you want to go though... IB standard and higher level physics use it, though it's a 1st year university text.

dont worry about physics. review grammar instead. it's more important

Simple Harmonic Motion (SHM) is all around us. Indeed, I understand that superstring theory embraces the notion of vibration in harmony. In fact the resonance of the superstrings is what gives rise to the manifestation of matter. Newton's First Law would be better expressed as "Every object moves in a manner dictated by simple harmonic motion."
