JEROME - Black holes do not exist

[Tubbythin]

Than why would object A with a large mass "fall" to the Earth with the same acceleration as object B with a small mass?


What is the cause?

Consider a body of mass m and a planet of mass M. Hold the body of mass m at a height above the body of mass M. Let go.

The force of gravity on mass m is:

F=GMm/r^2.

where r is the distance between the centres of the two masses.

But Newton's second law tells us that acceleration is proportional to the force applied and inversely proportional to mass, specifically

a=F/m.

Rearranging:

F=ma.

Equating the two equations for F we get

ma=GMm/r^2.

Cancelling the m's we get

a=GM/r^2.

That is, a is independent of m.

Pretty sure the moon's gravity is 1/6th of earth's. Different densities, and masses.

Read my above post. The moon gravity is 1/81 of the earth's, it is 1/6 on the surface of the moon, it is 1/81 3659 miles from the center of the moon.

The size of the moon is .27265 of the earth.

.27265 squrared equals .00743, .00743 time 1/6 equals about 1/81 of the earth's gravity.

That is why the moon is a good base, the gravity well is 1/81 of the earth's.

Daaaaaaaaaaa JEROME, is said, if you would read that the diffenece is a billionth of a billionth of a second, if not a lot less, and you think you will see this.

gravity

Or to make it simple for a simple mind:
The force of gravity on an object of mass m by an object of mass M is GMm/r²The acceleration of an object of mass m under a force F is: a = F/m
thus a = GM/r²
So objects A and B experience the same acceleration at the same distance from Earth.

I understand the equation, it is a representation of our observations.


Why does increased mass decrease the acceleration?

What force is working against the force of gravity?

 

[JEROME DA GNOME]

gravity

Gravity force which is based upon mass causes the force of gravity to be equal in different masses?

 

[JEROME DA GNOME]

gravity can be thought of as force per kilogram when considering the weight of an object. Therefore, feather or hammer, the force and mass increase proportionally and they accelerate at the same rate.

Newtons third. the force of gravity on the feather from the moon is equal and opposite to the force of gravity from the feather on the moon.

forces come in pairs.

The gravity of the Moon is pulling and the gravity of the feather is pushing?

 

[Tubbythin]

Why does increased mass decrease the acceleration?

It doesn't.

What force is working against the force of gravity?

What do you mean?

 

[Tubbythin]

The gravity of the Moon is pulling and the gravity of the feather is pushing?

No, the feather pulls the moon towards it (the feather), the moon pulls the feather towards it (the moon).

[JEROME DA GNOME]

It doesn't.

Than why does the gravity of a large mass not force the large mass to "fall" to the Earth with a greater acceleration than the gravity of a small mass?

Thanks, but we are talking about the force of gravity, not the relationship of various objects.

I thought we were past this several pages ago. You should read the thread.

No, the feather pulls the moon towards it (the feather), the moon pulls the feather towards it (the moon).

Correct.

[Tubbythin]

Than why does the gravity of a large mass not force the large mass to "fall" to the Earth with a greater acceleration than the gravity of a small mass?

Because you need a bigger force to accelerate a larger mass.

 

[JEROME DA GNOME]

No, the feather pulls the moon towards it (the feather), the moon pulls the feather towards it (the moon).

According to our understanding of the observation, correct.

Why does not the greater mass and thus the greater force of gravity within the hammer cause it to pull towards the Moon with a greater acceleration than the smaller mass and smaller gravity force of the feather?

 

[JEROME DA GNOME]

Because you need a bigger force to accelerate a larger mass.

A larger mass by the definition of the force of gravity has a larger force.

Because you need a bigger force to accelerate a larger mass.

A larger mass has according to our current understanding an inherently larger force.

 

[Tubbythin]

A larger mass by the definition of the force of gravity has a larger force.

Precisely. If it didn't then the lighter mass would fall quicker.

 

[Tubbythin]

A larger mass has according to our current understanding an inherently larger force.

And it needs this larger force to accelerate this larger mass to the same degree as the smaller mass.
