Speed of an Object

Speed is a way of measuring how quickly something is moving or being done, or something moving fast.

Calculation of Speed: We can calculate speed from the given formula.

                                 Speed:= ; frac{Distance}{Time}

The SI unit of speed is meter per second(m/s). We also calculate speed as kilo meter per hour(km/h).

Illustration 1: If a person covers a distance of 15 m in 5 seconds then find out the speed of the person.

Solution: As we know,   

 Speed:= ; frac{Distance}{Time}

Therefore,   

  Speed:= ; frac{15}{5}:=:3:m/s

Illustration 2:  A car is moving with a speed of 50 m/s for 20 seconds. Find out the distance covered by the car in given time period.
