Speed is the distance covered per unit time .

The speed of an object that is moving is a quantity that tells us how fast it is moving . Speed is a scalar quantity which does not represent the direction in which the object is moving .

Average speed gives an overall idea of how fast and object moved in the whole of the time interval under consideration .

__________________

The SI unit of speed is m/s

Speed is obtained by dividing distance by time . The unit of speed depends on the units of distance and time .

Like suppose an Air Jet Travels at an average speed of 8 km/s , then , the unit of speed will be kilometre per second or km/s .

As an example , suppose that the distance from New Delhi to Patna along the railway track is 1000 km . A train starts at 4 p.m. from New Delhi and reaches Patna at 8 a.m. the next day .

Thus , it takes 16 hours to cover 1000 km . The average speed during the 16 hours is

Avg. Speed → 1000 km / 16 h = 62.5 km/h

The difference between speed and average speed is that speed is a one time measurement of velocity while average speed is the median measurement of different speeds which basically is used simplify the varying speed to appear like a single speed only. To illustrate this see below example:

  • The standard unit for speed in science is meters per second. If, for example, a person runs 30 meters in 10 seconds, his speed is 3 meters per second.
  • If a person is running at varying speeds, then the relationship between speed, distance and time can only be used to calculate the average speed. A distance-time graph, which shows the speed varying as the time increases, is a good way to see how the speed of an object changes. If you add all these varying speed at any given time within the distance traveled and divide it to the number of varying speed you added together, then you will get the median speed or average speed which is basically used to simplify the different speed you have recorded.
