Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

6) In a downhill ski race, surprisingly, little advantage is gained by getting a running start.
