  2. Newton (unit) - Wikipedia

    en.wikipedia.org/wiki/Newton_(unit)

    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.

  3. Mass versus weight - Wikipedia

    en.wikipedia.org/wiki/Mass_versus_weight

    The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s 2. In trade and commerce and everyday use, the term "weight" is often used as a synonym for "mass".

  4. Weight - Wikipedia

    en.wikipedia.org/wiki/Weight

    The SI unit of weight is the same as that of force: the newton (N) – a derived unit which can also be expressed in SI base units as kg⋅m/s 2 (kilograms times metres per second squared). [21] In commercial and everyday use, the term "weight" is usually used to mean mass, and the verb "to weigh" means "to determine the mass of" or "to have a ...

  5. International System of Units - Wikipedia

    en.wikipedia.org/wiki/International_System_of_Units

    A combination of base and derived units may be used to express a derived unit. 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). [6]

  6. Pound (force) - Wikipedia

    en.wikipedia.org/wiki/Pound_(force)

    This is convenient because one pound mass exerts one pound force due to gravity. Note, however, unlike the other systems the force unit is not equal to the mass unit multiplied by the acceleration unit [11] —the use of Newton's second law, F = m ⋅ a, requires another factor, g c, usually taken to be 32.174049 (lb⋅ft)/(lbf⋅s 2).

  7. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  8. g-force - Wikipedia

    en.wikipedia.org/wiki/G-force

    The reason for the minus sign is that the actual force (i.e., measured weight) on an object produced by a g-force is in the opposite direction to the sign of the g-force, since in physics, weight is not the force that produces the acceleration, but rather the equal-and-opposite reaction force to it.

  9. Kilogram-force - Wikipedia

    en.wikipedia.org/wiki/Kilogram-force

    'weight'), is a non-standard gravitational metric unit of force. It is not accepted for use with the International System of Units (SI) [ 1 ] and is deprecated for most uses. [ citation needed ] The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a 9.806 65 m/s 2 gravitational field ( standard gravity ...
