Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
Lenz''s Law states that the Nature of induced emf in the coil is such that it opposes the causes of it. It can be explained by a simple understanding of Faraday EM induction ex
