Potential Energy - 7sciencewithmcmillan
... when a spring is stretched, work has been done to deform the spring, resulting in increased potential energy. When the spring is released, the potential energy will be transformed to kinetic energy as the spring snaps back into its original shape. This is also true of a spring that is compressed. St ...

Electrostatics
... Electrons are “boiled” off a heated cathode and emerge through a pinhole, being drawn toward the first anode, which is at a relatively small positive potential above the cathode. A second anode that is 20 kV above the cathode accelerates the beam up to speed. Determine the change in U of each e- . A ...

... Potential difference: ΔVab ≡ V ( r = b ) − V ( r = a ) = ∫ ∇V ( r )id = − ∫ E ( r )id This is true for any end-points a & b (and any contour from a → b). Thus the two integrands must be equal: E ( r ) = −∇V ( r ) Differential Version Now (for electrostatics): ∇ × E ( r ) = 0, Thus: ∇ × E ( r ) = ∇ × ...
