How to Calculate Instantaneous Velocity?

So we all know how to calculate velocity right?, Yes we do, but, when we calculate by dividing displacement by time taken we get the average velocity over the whole phase of the journey or time per... Read More »

What is the velocity of air in still air?

Speed of sound in still air is c ≈ 331 + 0.6 × T. T = Temperature. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.

How to Convert MPH to Velocity?

Speed and velocity are terms that are often interchanged. They are not, however, identical. Speed is a scalar entity that describes how fast a body is moving. Velocity is a vector, so it not only i... Read More »

RPM vs. Angular Velocity?

Revolutions per minute (rpm) and angular velocity, two measures of how fast a point rotates about another point, are used to solve physics, mechanical engineering and computer programming problems.... Read More »
