Walking Speed

Walking speed

Speed is a scalar quantity that represents the distance traveled by an object in a given unit of time.

In kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position).

Speed has the dimensions of a length divided by a time; the SI unit of speed is the metre per second.

An Italian physicist named Galileo Galilei is the first one to measure speed considering the distance covered and the time it takes.

Galileo defined speed as the distance covered per unit of time.

In equation form, this is:

where v is speed, d is distance, and t is time.

Knowing our walking speed is just easy. At first we think it was difficult but later on, as we measure and solve we find it fun and cool.

Here are some steps to know our walking speed:

Step 1: Measure a distance of 10 meters. Use a meter stick or a tape measure in measuring the distance.

Step 2: Have a table of data. Example:

Trials	Time	Distance	Speed
Trial 1
Trial 2
Trial 3
Trial 4
Trial 5

List all of the data that you have. 
To get the speed, use the equation:

To get the average speed you add all the time that you have in your 5 trials and then divide it by 5.

There you go, you will now have your average walking speed.

Cool isn’t it.

Knowing your average walking speed is very important because it is very useful to all of us. It is not only useful for the students like me but also to those people who are working.

By knowing your average walking speed you will know what is the exact time you will go out from your house and go to the school or any appointments by not getting late or being scolded.

Physics is a very useful branch of science because we will learn and discover a lot.

The things that we have learned and discover from physics are very useful in our daily living and in the future.
So, we should keep in studying physics!
