The dyne per centimetre is a unit traditionally used to measure surface tension. For example, the surface tension of distilled water is 71.99 dyn/cm at 25 °C (77 °F). [ 4 ] ( In SI units this is 71.99 × 10 −3 N/m or 71.99 mN/m .)
A newton is defined as 1 kg⋅m/s 2 (it is a named derived unit defined in terms of the SI base units). [1]: 137 One newton is, therefore, the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
The statsiemens or statmho is a unit of electric conductance equal to 1 statA/statV, corresponding to ~ 1.112 646 pS. [6] The stathenry is a unit of electric inductance equal to 1 statV·s/statA, corresponding to ~ 898.755 1787 GH. [7] [6] [a] The statfarad (statF) is a unit of electric capacitance equal to 1 statC/statV, corresponding to ~ 1. ...
The International System of Units, or SI, [1]: 123 is a decimal and metric system of units established in 1960 and periodically updated since then. The SI has an official status in most countries, including the United States , Canada , and the United Kingdom , although these three countries are among the handful of nations that, to various ...
A modern statement of Newton's second law is a vector equation: =, where is the momentum of the system, and is the net force. [ 17 ] : 399 If a body is in equilibrium, there is zero net force by definition (balanced forces may be present nevertheless).
An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g⋅cm 2 /s 2). It is thus equal to 10 −7 joules or 100 nanojoules in SI units. 1 erg = 10 −7 J = 100 nJ; 1 erg = 10 −10 sn⋅m = 100 psn⋅m = 100 ...
1 and q G 2 are the two electric charges, and r is the distance between the charges. This serves to define charge as a quantity in the Gaussian system. The statcoulomb is defined such that if two electric charges of 1 statC each and have a separation of 1 cm, the force of mutual electrical repulsion is 1 dyne. [1] Substituting F = 1 dyn, q G 1 ...
For example, the CGS unit of force is the dyne, which is defined as 1 g⋅cm/s 2, so the SI unit of force, the newton (1 kg⋅m/s 2), is equal to 100 000 dynes. On the other hand, in measurements of electromagnetic phenomena (involving units of charge , electric and magnetic fields, voltage , and so on), converting between CGS and SI is less ...
