    Falling Inertia
AI Thread Summary
In a vacuum, two objects of different masses will fall simultaneously when a supporting plank is removed, despite the heavier object's greater inertia. The heavier object does not take longer to start falling; both objects experience the same gravitational acceleration regardless of mass. The greater gravitational force acting on the heavier object balances its higher inertia, resulting in identical fall times. Therefore, both objects will begin to fall at the same moment, with no detectable delay. The discussion clarifies that inertia and gravitational force counteract each other, leading to uniform acceleration for all masses.

I've read other posts about this but I don't think this question was covered.

Say you have two objects with different masses in a vacuum sitting on some kind of plank. Next, you remove the plank from both at the same time. The heavier object has a greater inertia, which means that it has a greater tendency to resist change. Does that mean that it will take longer to start falling? By longer I mean something that can't been seen with the naked eye, but a computer can detect the difference in time to start falling.

It seems to me that if it doesn't start falling immediately, then it never will. Why would it "wait" before starting to fall?

Thanks guys. Your help is much appreciated.

To add, it may take more effort to get the heavier object to move, but the gravitational force acting on it is also larger! So can think of those two effects counteracting with one another.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
