Which property of matter changes depending on the gravitational pull

2 answers:

Answer: Mass– the amount of matter than an object is made of. Mass does not change with gravity. Weight– the amount of gravity acting on (pulling down on) an object (or mass). Gravity– a natural force that pulls objects downward.

The question is somewhat misleading.

Any lump of matter has a certain amount of mass. The mass is a property of that lump, and it doesn't change, no matter what happens to the lump or where it goes.

But the WEIGHT of the lump depends on what else is around, because the weight is the strength of the gravitational force on it, caused by some OTHER mass. The weight can change, because it depends on the OTHER mass.

The gravitational force changes the WEIGHT of the lump of matter, but that's not really a property of the matter.

The gravitational force between Mars and the Sun is $1.65\cdot 10^{21} N$

Explanation:

The magnitude of the gravitational force between two objects is given by the equation:

$F=G\frac{m_1 m_2}{r^2}$

where

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

In this problem, we have:

$m_1 = 1.99\cdot 10^{30} kg$ is the mass of the Sun

$m_2 = 6.39\cdot 10^{23} kg$ is the mass of Mars

$r=229\cdot 10^6 km = 229\cdot 10^9 m$ is the average distance Mars-Sun

Substituting into the equation, we find the gravitational force:

$F=(6.67\cdot 10^{-11})\frac{(1.99\cdot 10^{30})(6.39\cdot 10^{23})}{(229\cdot 10^9)^2}=1.62\cdot 10^{21} N$

So, the closest answer is

$1.65\cdot 10^{21} N$
