Confusion in definition of Potential Energy
Potential energy is defined like this. $ΔP.E=-W_{AB}$. This means that the potential energy at point A minus potential energy at point B should equal the negative of the work done by a conservative ...

Concept of Gravitational potential energy
Change in Potential energy corresponding to a conservative force is defined as $$\Delta U = U_f - U_i=-W_f$$ and gravitational potential energy is $$\Delta U = U_f-U_i = -W_g $$ Suppose a mass $m_1$ ...

Better understanding of the definition of Gravitational Potential as the improper integral $\frac{1}{m}\int^x _{\infty}G\frac{Mm}{x^2}dx$
According to Wikipedia "The gravitational potential $V$ at a distance $x$ from a point mass of mass $M$ can be defined as the work $W$ that needs to be done by an external agent to bring a unit ...

What is the height in the potential energy formulation? [duplicate]
Most examples I've seen describe the (gravitational) potential energy e.g. with an example of a ball thrown upwards, and explain how the sum of the ball's kinetic and potential energy is constant at ...

The reference point of potential energy
In one dimension (I am not familiar with multivariable calculus), potential energy is defined as
$$E_p = -\int F \ dx$$
This is an indefinite integral, and the integration constant $C$ is involved ...

Potential energy definition in terms of work done
It's true the source might not be the most reliable of all, however it states that:
The potential energy $U$ is equal to the work you must do to move an object from the $U=0$ reference point to the ...

Potential energy $= mgh$, what is $h$?
NOTE: when I say potential energy I mean gravitational PE
The formula for potential energy is P.E = mgh.
What is h referring to? Height, obviously.
Consider the example: What is the potential ...
