Answer:
Because the mass of the the earth is way bigger than the mass of a classmate
Explanation:
Formula for force of gravity is;
F = Gm1•m2/r²
Where m1 and m2 are the two objects masses in question.
So, m1 may be your mass while m2 may be either the mass of the earth or your classmate.
The bigger the mass of m2, the more the force of gravity
Mass of the earth is about 5.97 × 10^(24) kg is which is so much more bigger than that of the classmate which is a human being.
Therefore, the reason why you may feel the effect of the gravitational forces between you and Earth, but not between you and a classmate is probably because the mass of the the earth is way bigger than the mass of a classmate
Due to relative lower mass of classmate as compare to the earth, you do not feel gravitational force between you and your classmate.
Gravitational force is a natural attracting force that will be present on each and every body which possesses mass, and it is calculated as follow:
[tex]\[{\rm{F = G}}{\rm{.}}\frac{{{{\rm{m}}_{\rm{1}}}{{\rm{m}}_{\rm{2}}}}}{{{{\rm{r}}^{\rm{2}}}}}\][/tex], where
F = gravitational force
G = universal gravitational constant
m₁ = mass of one object
m₂ = mass of another object
r = distance between the two objects
From the above expression it is clear that gravitational force is directly proportional to the masses of the object.
So the mass of the earth is very high as compare to the mass of any our classmate and this is that reason you don't feel the effect of gravitational forces between you and classmate.
