Newtons laws of motion
Briefly illustrate all the Newton s laws of motion?
Expert
The Newton's laws of motion are as follows:
a) The body at rest will remain at rest and the body in motion will always remain in motion, until and unless acted on by the external force. (That is, Law of inertia)
b) The rate of change of momentum of a body is proportional to the resulting force acting on the body in similar direction as its motion. (That is, F = ma)
c) For all action there is an equal and opposite reaction.
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.

Ultraviolet catastrophe: It is the shortcoming of Rayleigh-Jeans formula that attempted to explain the radiance of a blackbody at different frequencies of the electromagnetic spectrum. This was clearly wrong since as the frequency rose, the radiance r
Transition temperature: The temperature (that is, dependant on the substance comprised) below that a superconducting material conducts electricity with zero resistance; therefore, the temperature above which a superconductor lose its superconductive p

Centrifugal pseudo force: A pseudo force which takes place whenever one is moving in uniform circular motion. One feels a "force" directed outward from the center of the motion.
Radian: rad: The supplementary SI unit of the angular measure stated as the central angle of a circle whose subtended arc is equivalent to the radius of the circle.
Twin paradox: One of the most well-known "paradoxes" in history, predicted by Sir Einstein's special theory of relativity. It takes two twins, born on similar date on Earth. One, Albert, leaves home for a trip about the Universe at very high speeds (v
