Speed of an Object
Speed of an Object
Speed :
Speed is the distance traveled per unit time. It is a way of measuring how quickly something is moving or being done, or something moving fast.
Calculation of speed:
The instrument/ meter measuring the speed of the vehicle is called a speedometer. The distance traveled by the vehicle is given by an instrument called odometer.
We can calculate speed from the given formula.
The SI unit of speed is meter per second(m/s). We also calculate speed as kilo meter per hour(km/h).
We can calculate the speed of an object if we know the distance it travels in a given amount of time. Let us see how this is done.
Illustration 1:, In a 100 m race Shreya ran the race in 20 s. What is Shreya’s speed?
Solution:As speed is the distance traveled in unit time, Shreya’s speed is the distance traveled in unit time. Shreya’s speed can be calculated by dividing the distance she ran by the time she took to cover that distance. Therefore, Shreya’s speed is:
Speed is a way of measuring how quickly something is moving or being done, or something moving fast.
