Physics

The distance traveled when the object covers half the circle is equal to half of the circumference of the circle. The formula for the circumference of a circle is:

Circumference = 2πr

 

So, the distance for half of the circle is: Distance = πr

 

Then, displacement is the straight-line distance between the starting point and the ending point. If the object covers half the circle, the displacement is the diameter of the circle, which is: Displacement = 2r

 

Now, we can calculate the ratio of distance to displacement:
