Einstein put forth special relativity, which explains motion at near-light speeds. Although there are many consequences of Special Relativity, this complex theory consists of only two postulates ...

The rate of air flow varies depending on the properties of the channel through which it flows; narrow channels increase its velocity, and wide channels decrease it. Why does wind blow in gusts and ...

Published values for pressure losses in elbows are based on the assumption of a uniform velocity profile entering the elbow, but the velocity profile at the outlet of a fan is not uniform and an elbow ...

A body is said to be moving with uniform motion if it undergoes equal displacement in equal interval of time. Average velocity is defined as the change in position or displacement (Δx ...

An object is said to be moving with non – uniform accelerated motion if the change in velocity of an object in each unit of time is not constant. CBSE Class 11 Physics Syllabus 2017 - 2018 ...
