Pendulum energy exchange

Work, Energy and Power · ch06-work-energy-and-power

KE and PE swap as a pendulum swings; their sum is constant.

Controls

Effective stiffness40 N/m

Mass m1.00 kg

Amplitude A0.20 m

Live values

E = \tfrac{1}{2} k A^2

Try this: KE and PE oscillate but their sum E is conserved.
