On calculation, the Average speed = 1 m/s, average velocity = 0 m/s

Calculation

Average speed = [tex]\frac{total distance}{total time}[/tex] = [tex]\frac{50+50}{100}[/tex] = 1m/s

Average velocity =[tex]\frac{total displacement}{total time}[/tex] = 0/100 = 0 m/s

What is Average speed?

The overall distance that an object covers in a given amount of time is its average speed. A scalar value represents the average speed. This average speed has no direction and is indicated by its magnitude.

The formula for an object’s general speed average is [Average Speed = Total Distance Traveled Total Time Taken]. M/s is considered as the SI unit for average speed.

What is Average velocity?

Average speed is determined by dividing the total distance you travelled by the total time, whereas average velocity is determined by dividing your displacement (a vector pointing from your initial position to your end position) by the whole time.
