Unleashing the Power of Physics: Discovering the Conversion of 1 Newton to Dyne in 4 Different Ways

Understanding force in physics requires familiarity with different units of measurement. One such unit is the dyne, which is a measure of force in the centimetre-gram-second (cgs) system of units, denoted as "dyn." A dyne is equivalent to 10 -5 newtons and can be defined as the force required to accelerate one gram of mass at a rate of one centimetre per second squared.

To convert the SI unit of force, which is measured in kilograms, metres per second (kg m ${s}^{-2}$), into the CGS equivalent, we use the formula: 1newton = 100000 $g cm { s }^{ -2 }$. Therefore, 1 newton equals ${ 10 }^{ 5 }$ dynes.

The dyne was first proposed as a unit of force in 1873 by the British Association for the Advancement of Science. It is a derived unit in the CGS system of units, which predates the modern International System of Units (SI).

On the other hand, the Newton is the standard unit of force in the SI system, named after Isaac Newton, who contributed significantly to classical mechanics. One Newton is the force needed to accelerate one kilogram of mass at one metre per second squared in the direction of the applied force. This can be understood as a change in velocity per time, where velocity increases by 1 metre per second every second.

The MKS system of units standardized the unit of force as the amount required to accelerate one kilogram of mass at the rate of one metre per second squared in 1946. The 9th Conférence Générale des Poids et Mesures (CGPM) Resolution 7 adopted the name Newton for this force in 1948. This established the Newton as the standard unit of force in the SI system used today.

To clarify, the Newton is the basic unit of force, while the dyne is a derived unit in the CGS system. It is crucial not to confuse these units since their values differ considerably. Remembering the relationship between these units is essential since it is used in many questions.
