Newton just claimed that was true. We have made millions of measurements which support the theory. But I know no way of proving it. A separate question is whether inertial mass equals gravitational mass. Again, all the measurements we've ever taken support the idea, but we know no way to prove it.

Mass is related to gravity. If you were on a 10 G world you would be more massive and thus compressed into a smaller space. A black hole is a massive object that is compressed into a small space. Does a black hole have inertia? It has gravity. It is so massive that the c does not escape it. But is it's inertia = to it's mass? If so, then it's mass is bigger then the speed of light. Proving that the speed of light can be exceeded.

Inertia is the characteristic of matter that want to keep its kinetic state constant. in simple words it posses difficulties in velocity changes as far as direction and magnitude is concerned. if it is at still it will try to remain at still and if it id moving it will try to preserve its kinetic state upon any stimulus.

now mass an dinertia are direclty related. the greter the inertia the greater the mass and vice versa.




now if you have the same force.acting on different masses the results will be different.
esspecialy due to the F * m *a

but due to the theorem of conservation of kinetic energy that in other words also states that it will take more power over a distance to change the kinetic energy of and object that it is heavier.


friction is a measure as well


for same coefficient friction is greater for heavier bodies meaning it is more difficult to move them (change their kinetic state)

look, if u wanna put a heavy carriage in motion u need more force
if u wanna put a lighter carriage in motion u need lesser force.
so,thats it. it proves that inertia or ability to change the state of rest or motion of a body depends on mass.

take 2 foot-balls inflate 1 with helium & the other with air & since helium is not as dence as air the 1 filled with air can be thrown with a higher eficienny rate than the 1 filled with helium

as we have law of inertia,a body at rest will remain at rest and a body at motion will remain at motion unless it is compelled by an external agent to change its state or motion
f(force)=m(mass)* a(Acceleration)

as it's stated in law that a body remains in rest or motion unless compelled to change it's state by an applied force.so it can be
f=ma
f=m(v-u)/t
if we consider force to be equal tobe 0 than
0=m(v-u)/t
m can't be 0
0*t=v-u
0=v-u
v=u

when you move something heavy,
(BIG MASS),
you can't put it into motion right away...
so...
greater mass, greater resistance to motion (inertia)..
