Energy and Work in Uniform Circular Motion (HSC SSCE Physics): Flashcards

Sum of kinetic and potential energies

$K = \frac{1}{2}mv^2$

Constant (speed is constant)

$U_g = mgh$

Constant (height doesn't change)

Zero (energy is constant)

Perpendicular (force to centre, velocity tangent)

Zero ($W = Fs = 0$)

Zero (returns to initial position)

$h_{\text{top}} = h_{\text{bottom}} + 2r$
