Answer 1

Answer:

We use suitcase with wheels because it reduces friction.

Explanation:

Actually, when we use suitcase with wheels, friction is produced

[that friction is called rolling friction],

but that friction is comparatively less than the normal friction that we face in our day-to-day life.

Always remember:-

Normal Friction  > Rolling Friction

[therefore, using wheels makes it easy to drag suitcase from one place to another.]
