Amonton’s Law of Friction

Amonton’s Law of Friction are named after the French physicist Guillaume Amontons, who discovered these laws. There are two laws given by Amontons i.e.

• Amonton’s First Law
• Amonton’s Second Law

Let’s discuss these laws in detail as follows.

Amonton’s First Law

The Amontons’ First Law, sometimes known as the Amontons’ Friction Law, is one of the basic theories governing frictional forces. It states that the friction force is directly impacted by the applied normal force. In terms of math, it can be expressed as:

F ∝ N

Where:

• F = The resistive force, or friction, and
• N = is the amount of force an average person would apply to the floor or a push-up board during a push-up.

Amonton’s Second Law

Amonton also put up another important theory regarding friction, which is known as the Angle of Friction or the Second Law of Amontons. The frictional force, according to this equation, is directly determined by the normal force between the bodies rather than by the apparent area of contact between surfaces. The expression in mathematics is as follows:

F ∝ tan(θ)

Where,

• F It is friction that opposes your moving forward, and
• θ is the angle of intersection of the surfaces.

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.
