Question

Sir it is said that"path length of travel is useful in determining"

1)how long a journey might take,

2)wear and tear of a vehicle.

Sir can you please explain how ?

Answer 1

In physics, there are two definitions for "path length." The first is defined as the total distance an object travels. Unlike displacement, which is the total distance an object travels from a starting point, path lengthis the total distance travelled, regardless of where it travelled.

a) So by knowing the path length that is total distance in a travel we can easily understand how long a journey take...

B) vehicle'' wear and tear depends on how much distance vehicle covered....to know that we need to know path length.
