What Does Potential Energy Mean? Potential energy is energy held by an object that has yet to be released. Potential energy is often due to an object's height in a gravity field, electric charge, or stresses within the object. It is often referred to as "stored energy" or classified by...
Given that we are talking about a theory of physics, the Lorentzian arc length is the one that has physical meaning in the theory; the Euclidean arc length does not. So using the term "arc length" for the Euclidean one in the context of the physical theory is at least as confusing as...
How far away does the cannonball land? Calculate the impact speed (ignoring air resistance) of an object dropped from a specific height or the maximum height reached by an object (ignoring air resistance), given the initial verti...
[Doesn't that mean that the fluid never changes speed?] So how does the idea of steady flow help us figure out the change in energy of the big winding system of fluid? Consider the diagram below. Our energy system consists of the greyed out fluid (volume 1, volume 2, and all fluid...
