Let's learn more about speed.
Speed is a special kind of rate. When an object is moving, the speed of the object is the rate of distance covered per unit time.
In a nutshell, speed is the distance travelled per unit time.
Do remember the following three formulas well.
Note that the units used in D, S & T must correspond to one another.
Here's a video to help you remember how to get the formulas...
Oh yes! Just a question.
There are many different types of units that can be used for speed e.g. m/s, km/h, m/min, cm/s
How do we know when which units are more appropriate?
And now, it's time to learn about the amazing wonders of Mother Nature! :)
The speeds indicated in the video above is the average speed. This is because the speed throughout a journey may not be constant all the time.
Average speed = total distance covered ÷ total time taken
The average speed is not the sum of two speeds divided by two.
