Magnitude (force)

from Wikipedia, the free encyclopedia

This is a compilation of forces of different magnitudes for comparison purposes. The information is often to be understood as “typical values”; the converted values ​​are rounded.

Basic unit of force in the international system of units is 1  Newton ( unit mark N ), the symbols F .

Forces less than or equal to piconewtons

  • 3.6 · 10 −47 N: gravity between proton and electron in the hydrogen atom .
  • 8.9 · 10 −30 N: weight of an electron on the earth's surface.
  • 1.6 · 10 −26 N: weight of a hydrogen atom on the earth's surface.
  • 5 · 10 −24 N: Force that was necessary to synchronize the atomic oscillation of an ultracold atom in a Paul trap with an external radio frequency.

1 piconewton is a trillionth of a newton (10 −12 N).

Nanonewtons

1 nanonewton (1 nN) is one billionth of a newton (10 −9 N).

Micronewtons

1 micronewton (1 μN) is a millionth of a newton (10 −6 N).

Millinewton

1 millinewton (1 mN) is a thousandth of a newton (10 −3 N).

Newton

  • 1 Newton (1 N) is the amount of force needed to provide a dormant body mass kg 1 within one second uniformly to the speed to accelerate .
  • 1 N is the weight that acts on a body weighing 102  grams (e.g. a chocolate bar with packaging).
  • 9.81 N is the weight of a body with a mass of 1 kilogram on earth.
  • 720 N: Average bite force of a person.

Kilonewtons

1 kilonewton (1 kN) is a thousand newtons (10 3  N).

  • 1 kN roughly corresponds to the weight that acts on a mass of 100 kg.
  • 9 kN corresponds roughly to the bite force of a full-grown alligator.
  • 9.81 kN is the weight of the mass of one ton on earth.
  • 100 kN: The force exerted by the seat belt and airbag on a car occupant when a car hits a rigid obstacle at around 100 km / h.
  • 890 kN: Maximum driving force of a large diesel locomotive.

Meganewton

1 meganewtons (1 MN) is 1 million newtons (10 6  N).

Giganewton

1 Giganewtons (1 GN) are one billion Newtons (10 9  N).

Teranewton

1 Teranewton (1 TN) is one trillion Newtons (10 12  N).

Petanewtons and Beyond

1 petanewton (1 PN) is 1 quadrillion newtons (10 15  N).

  • 2.0 · 10 20  N: gravitational force between the earth and the moon
  • 3.5 · 10 22  N: gravitational force between earth and sun
