Difference between Speed and Velocity: Speed and velocity are the most basic concepts from Physics. They form the part of your Physics textbook right from early classes when Physics is introduced as a ...

It is not only moving objects whose speed can vary. The speed of the wind and the speed of sound also vary. A typical value for the speed of sound in air is about 330 m/s.

Speed of a body is the distance travelled by it per unit time and Velocity of a body is the distance travelled by it per unit time in a given direction. This article deals with why Speed and Velocity ...
