Answered

Which of the following describes kinetic friction?

A. Friction between moving parts.
B. A pushing force.
C. Heat that must be dissipated quickly.
D. Friction between non-moving parts.



Answer :

Final answer:

Kinetic friction opposes the motion of two systems in contact and moving relative to each other by converting kinetic energy into heat.


Explanation:

Kinetic friction occurs between two surfaces that are in contact and moving relative to each other. It is a force that opposes the motion of these systems by converting kinetic energy into heat.

For example, when a sled slides on the ground, the friction between the sled and the ground is an instance of kinetic friction.
