What are Laws of Frictions?
The laws of friction explain how friction acts in relation to normal force and motion. There are five main laws of friction, which include:
- The First Law of Friction: Friction is proportional and perpendicular to the normal force acting on an object.
- The Second Law of Friction: The force of friction is independent of the apparent area of contact between the surfaces.
- The Third Law of Friction: The force of friction is independent of the sliding velocity between the surfaces.
- The Fourth Law of Friction: The force of friction is independent of the direction of sliding.
- The Fifth Law of Friction: The force of friction is directly proportional to the normal force acting on an object.
Laws of Friction
Friction is a fundamental force that affects our everyday lives. When we slide a book across a table or walk on a slippery surface, friction comes into play. There are various laws which govern the phenomenon of friction such as Amonton’s and Columnb’s Laws. In this article, we will discuss all the laws which help us understand the concept of Friction.
