If the car is on or near the Earth's surface, then it weighs 3,086.5 pounds. (rounded)
On earth, 8 kg of mass weighs 78.4 newtons (17.64 pounds).
If it weighs 98 newtons on Earth, then we know that its mass is about 10kg. If that figure is its weight somewhere else, then its mass is something else.
On earth the rock has a mass of 9.6kg
mass only because air weighs nothing
If the car is on or near the Earth's surface, then it weighs 3,086.5 pounds. (rounded)
On earth, 8 kg of mass weighs 78.4 newtons (17.64 pounds).
About 1998 kilograms on Earth.
Since Newton is the unit for Force. And as we know "Force = Mass * Acceleration" Newton = Kg * 9.81 Therefore , Kg = Newton / 9.81 Hence, Mass = 22000/9.81 = 2200 (approx)
On Earth, 1,500 kg of mass weighs 14,710 newtons.
The mass of an object that weighs 39.2N on earth is 4kg
A proton weighs 1 atomic mass unit.
So, 1lb = 0.45kg 2100lbs = 845kg. No need for rounding, it's spot on.
The mass of an object that weighs 600N on earth is 61.18kg
Its mass is 3.28kg
Weight does change when you increase distance from a source of gravity since the force felt is inversely proportional to the square of the distance, but mass by definition does not, it still has the same mass, sometimes called inertial mass - so even if the car were way out in space it would still have a mass of 860kg.
6 pounds = 2.72155422 kilograms
