An introduction to centripetal force: Definition, formulas, and examples
In physics, the centripetal force is used widely for circular motion. Centripetal force is a general type of force and is usually used for...
How to calculate the work done by force?
When the force moves an object to the distance t is called work done. It is the most common term used in physics or...
Beats & Doppler Effect
Beats
The phenomenon of wavering of sound intensity when two waves of nearly same frequencies and amplitudes traveling in the same direction, are superimposed on...
Standing Waves and Normal Modes
The interference of two identical waves moving in opposite directions produces standing waves. For a string with fixed ends, the standing wave is given...
Reflection of waves
Reflection of waves
A part of the wave is reflected and a part is transmitted into the second medium. If a wave is an incident...
The Principle of Superposition of Waves
The Principle of Superposition of Waves
The net displacement of any element of the string at a given time is the algebraic sum of the...

Displacement Relation in a Progressive Wave
Progressive Wave:
A wave that travels from one point of the medium to another is called a progressive wave. A progressive wave may be transverse...
Waves & Types of Waves
Waves
A wave is a disturbance that travels or propagates and transports energy and momentum without the transport of matter. The ripples on a pond,...
