Hace 2 días · Combinations of base and derived units may be used to express other derived units. For example, the SI unit of force is the newton (N), the SI unit of pressure is the pascal (Pa)—and the pascal can be defined as one newton per square metre (N/m 2).

The unit is named after Blaise Pas­cal, noted for his con­tri­bu­tions to hy­dro­dy­nam­ics and hy­dro­sta­t­ics, and ex­per­i­ments with a barom­e­ter. The name pas­cal was adopted for the SI unit new­ton per square metre (N/m2) by the 14th Gen­eral Con­fer­ence on Weights and Mea­suresin 1971.

The pas­cal can be ex­pressed using SI de­rived units, or al­ter­na­tively solely SI base units, as: 1. 1Pa=1Nm2=1kgm⋅s2=1Jm3{\\displaystyle {\\rm {1~Pa=1~{\\frac {N}{m^{2}}}=1~{\\frac {kg}{m{\\cdot }s^{2}}}=1~{\\frac {J}{m^{3}}}}}} where N is the new­ton, m is the metre, kg is the kilo­gram, s is the sec­ond, and J is the joule. One pas­cal is the pres­...

The unit of mea­sure­ment called an at­mos­phere or a stan­dard at­mos­phere (atm) is 101325 Pa (101.325 kPa). This value is often used as a ref­er­ence pres­sure and spec­i­fied as such in some na­tional and in­ter­na­tional stan­dards, such as the In­ter­na­tional Or­ga­ni­za­tion for Stan­dard­iza­tion's ISO 2787 (pneu­matic tools and com­pres­s...

The pas­cal (Pa) or kilo­pas­cal (kPa) as a unit of pres­sure mea­sure­ment is widely used through­out the world and has largely re­placed the pounds per square inch (psi) unit, ex­cept in some coun­tries that still use the im­pe­r­ial mea­sure­ment sys­tem or the US cus­tom­ary sys­tem, in­clud­ing the United States. Geo­physi­cists use the gi­ga­...

Hace 3 días · Young's modulus , the Young modulus, or the modulus of elasticity in tension or compression (i.e., negative tension), is a mechanical property that measures the tensile or compressive stiffness of a solid material when the force is applied lengthwise.

5. ### en.wikipedia.org › wiki › MomentumMomentum - Wikipedia

Hace 3 días · In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second. Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it.
