AI Thread Summary
The discussion clarifies the relationship between force and height when lifting an object, emphasizing that the work done (W) is equal to the gravitational potential energy gained (mgh). The equation W = Fd is confirmed, where F represents the weight of the object (F = mg). Participants note that while force is related to weight, the work done to lift an object is calculated using the height lifted. The conversation highlights a common confusion between force and work, ultimately reinforcing that the work done against gravity is indeed mgh. Understanding this relationship is crucial for accurately calculating energy changes when lifting objects.

Is the force done on a lifted object equal the weight of the object in Newtons times the height lifted?
F=mgh?
I would have used this but I noticed it was the same equation for gravitational potential energy (or just potential energy)...So I thought I would ask you all after failing to find it online.

I suspect you meant work instead of force.
F=mgh?

Yes, the work you must do to lift an object equals the increase in gravitational potential energy.
 
no, no I was talking about force. I am trying to find the change in gravitational potential energy from a 2.0 object being lifted 3.5 meters.
So I thought I would find Ke at the bottom.


\sum w=\Delta ke

W=F.d

So I want to know if F=mgh
:)

If I am completely full of crap and doing it wrong please tell me o.O

No, F = mg (the weight). (Assuming you are doing the minimum work to overcome gravity.)

So W = Fd = mgh.
 
oh, duh xD I feel stupid now. thank you.
 

Thread 'Is calling fictitious forces not real just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
