Dyne

In physics

Physics

Physics is the natural science which examines basic concepts such as energy, force, and spacetime and all that derives from these, such as mass, charge, matter and its Motion ....
, the dyne (symbol "dyn", from Greek d??aµ?? (dynamis) meaning power, force) is a unit

Units of measurement

The definition, agreement and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day....
of force specified in the centimetre-gram-second
Centimetre gram second system of units

The centimetre-gram-second system is a metric system of units of measurement based on centimetre, gram, and second. All of CGS mechanicss are unambiguously derived from these three base units, but there are several alternative variants of extending the CGS system in electromagnetism....

s. Equivalently, the dyne is defined as "the force required to accelerate a mass

Mass

In physical science, mass refers to the degree of acceleration a body acquires when subject to a force: bodies with greater mass are accelerated less by the same force....

Gram

The gram , ; symbol g, is a Physical unit of mass.Originally defined as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice" , a gram is now defined as one one-thousandth of the SI base unit, the kilogram, or Scientific notation kg, which itself is...

1 dyn = 1 g·cm/s² = 10^-5 kg·m/s² = 10 µN

The dyne per centimetre is the unit usually associated with measuring surface tension

Surface tension

Surface tension is an attractive property of the surface of a liquid. It is what causes the surface portion of liquid to be attracted to another surface, such as that of another portion of liquid ....
