Question

Evil space aliens drop you and your fellow astronomy student 1 km apart out in space, very far from any star or planet. Discuss the effects of gravity on each of you.

Answer 1

The force of gravity will be very weak as can be seen from the above calculations.

Step-by-step explanation:

Universal law of gravity states that

The force of gravity is proportional to the masses' product and divided by the square of the distance between the two objects.

`F=G(M_1M_2)/(r^2)`

Where

G = Gravitational constant = 6.674×10⁻¹¹ m³/kg⋅s²

M₁ = Mass of object one

M₂ = Mass of object two

r = Distance between the two objects.

So,

`F=6.674* 10^(-11)(M_1 M_2)/(1000^2)\\\Rightarrow F=6.674* 10^(-18)* M_1 M_2`

In the situation presented here the force of gravity will depend on the mass of you and your fellow astronomy student in kg. The more the mass the stronger the force of gravity will be. The force of gravity will be very weak as can be seen from the above calculations.
