the soles of the shoes are wornout

Answer 2

It can be sometimes damaging as it reduces the object's motion.

• It is harmful in many ways as -

1. It lowers the speed of moving things and can even bring them to a complete stop.
2. It also leads to the production of heat between the items. As a result, energy is neglected in the machinery.
3. Because of this phenomena, the machine parts often wear out.
4. Because the force resists a body's motion, it takes more energy to overcome the friction.
5. Forest fires are also caused by friction between the tree's branches and leaves
