100 kilos to newtons
In physics there is a certain unit for every quantity. The force is usually given in Newtons and must not be confused with the quantity mass. Converting 100 kilos into the unit Newton is not difficult and should be known to every student.
Risk of confusion - mass and strength
- Many students confuse in the physics the quantities of mass and force. While the mass is given in kilograms (kg), the force is expressed in the unit Newton (N). Here 1 N = 1 kg m / s². In addition, the mass is abbreviated as m, whereas the force is abbreviated as F.
- Another essential difference between these two quantities is the number 9.81 N - this is the factor of gravity on the earth's surface. But keep in mind that the spatial factor can vary - on the moon, for example, gravity is lower than on earth.
- On the other hand, the mass does not decrease on the moon. This is because it is a location-independent quantity that can be calculated using the formula m = V • ρ (mass = volume • density).
Conversion - 100 kilos in newtons
- The formula of the force can also be deduced from the formula of the mass m = V • ρ. Since the spatial factor makes the difference between mass and force, the formula for the force is therefore: F = m • g (force = mass • spatial factor).
- If you know the location factor, you can easily convert the unit Newton to Kilo. On the earth's surface, for example, 1 kg is roughly equivalent to 9.81 N. Consequently, 100 kilos are equivalent to 981 Newtons (or more precisely: 100 kg = 980.665 N).
- If you have a body on earth with a mass of m = 60 kg, simply multiply this value by the location factor g. The result is a weight of 588.6 N at 60 kg • 9.81 N / kg.
- On the moon, the force of gravity is 6 times lower and is therefore approx. 1.62 N. Here a body with a mass of 60 kg would have a weight of just 97.2 N.
