Did you know that the Earth weighs about 6 000 000 000 000 000 000 000 000 kilograms? Some people have calculated how heavy the earth is.
Below is the calculation with explanations:
We can calculate the Earth's mass using the gravity that the earth exerts on objects.
Newton taught us that at ' bulbs ' we can act as if all the masses are in the center of the sphere.
The following equation expresses gravity between 2 spheres.
F = G * M1 * M2/R2
R is the distance between the 2 spheres.
G is a constant: 6.67259 x10-11m3/s2 kg.
M1 and M2 are the masses of the 2 bulbs that attract each other F is the force which the bulbs attract each other
We now assume that M1 is the Earth and M2 is a sphere of 1kg.
The strength with which they attract each other is 9.8 kg * m/s2-This can be calculated by dropping the sphere of 1kg and then measuring its acceleration (9.8 m/s2)-.
The radius of the earth is 6.4 million meters and if we fill it in the formula and fix it for M1, we find that the mass of the Earth is 6, 000, 000, 000, 000, 000, 000, 000, 000 kilograms (6th + 24 kg).
