what is the meaning of formula for speed. Average speed measures the average rate of speed over the extent of a trip. The c stands for the speed of light a universal constant so the whole equation breaks down to this.
As modeled in the International Standard Atmosphere dry air at mean sea level standard temperature of 15 C 59 F the speed of sound is 3403 meters per second 11165 fts. Speed is known as distance traveled per unit of time. Dimensional formula of time M 0 L 0 T 1.
Velocity is a vector quantity.
It is how fast an item is moving. Hence speed is a scalar quantity and it can never be a negative value. This is the definition of speed but hardly enough to be sure students know about speed and its relationship to velocity and acceleration. The c stands for the speed of light a universal constant so the whole equation breaks down to this.
