Qualitative question about inertia and gravity

[LeHotDoge]

Homework Statement

Why does an object with a bigger mass(more inertia) accelerate the same as an object with a lesser mass(less inertia) when in free fall?

Well, what do you think?

Well, what do you think?

I think I'm confused because an object with more inertia should resist it's change in state of motion more

 

[brainpushups]

Great. So what must that say about the force of gravity?

the force of gravity is constant and causes a downward or negative acceleration.

 

[haruspex]

the force of gravity is constant

The force is constant for a given mass?, or are you saying it's the same for all masses?

Ermmm...a no would do. Remember Newton's law of universal gravitation explicitly indicates that distance between is crucial to the magnitude of the gravitational force two masses experience.

Analyze... more mass, greater inertia(or vice versa). We expect the more massive body to resist acceleration compared to the other when acted on by the same force. This is the case we havs two different bodies of different inertia, but their accelerations are equal. This directly means a difference in...

well the force of gravity is m*g , so a greater mass would have a greater force of gravity. Acceleration of an object is directly proportional to force(in this case force of gravity) and inversely proportional to mass, now I understand.
