When it reaches position B, all potential energy has converted into kinetic energy. As the pendulum moves from B to C, the kinetic energy is converted back into potential energy. 7. Conservation of Energy: Throughout the motion of the pendulum, the total mechanical energy (sum of potential ...
Experiments powersciencelike gasoline powers a car. If you have a theory about how the world works, it's a basic rule of science that you need to test it with an experiment. If your experiment confirms the theory, great; if not, refine your theory and do some more experiments. Although ...

And the conservation of energy equation: {eq}\frac{L}{2}\left ( \frac{d \theta}{dt} \right )^2 + g(1- \cos(\theta))=E {/eq} a. For what range of total energy values E does the pendulum "loop"? Explain. b. Show that the "separatrix" (the curve that sep...
The first law of thermodynamics is the application of the conservation of energy principle to heat and thermodynamic processes. The first law makes use of the key concepts of internal energy, heat, and system work. It is used extensively in the discussion of heat engines. The standard unit for...
