Question

Friction is a force that resists the relative motion of two objects in contact.

Why is the speciality of putting the word relative motion without putting motion

Answer 1

Step-by-step explanation:

Friction is a force that opposes the motion or potential motion of two items that come into contact. The word "relative motion" emphasizes that friction resists the motion of the objects with respect to one other, and it emphasizes that friction specifically operates against the motion or potential motion between two objects in contact.
