GENERAL EXPRESSION FOR A PROGRESSIVE WAVE IN A NON DISPERSIVE MEDIUM
A non dispersive medium is one in which the properties of the waveform with regards to the propagation of the wave remains same such that the wave propagates without a change in the shape of the waveform. In […]
HOOKE’S LAW
What is Hooke’s Law ?
One of the properties of elasticity is that it takes about twice as much force to stretch a spring twice as far. That linear dependence of displacement upon stretching force is called Hooke’s law.
A spring is an example of an elastic object […]
KINEMATICS
What is Kinematics?
Kinematics is that branch of mechanics that deals with the motions of objects without being concerned with the forces that cause the motion. In this latter respect it differs from dynamics, which deals with the forces that cause motion
THE CONCEPT OF REST AND MOTION
A body is said to be at rest if it […]
BASIC PHYSICS
UNITS
Physics, as a subject deals with the laws of nature, this study is quantitative and requires the measurement and comparison of physical quantities. In order to solve this problem we use standard units. A unit is nothing but a specified measure of a physical quantity, such as length, area, volume, mass, time etc. which […]
