The Law of Conservation of Energy
... Water can produce electricity. Water falls from the sky, converting potential energy to kinetic energy. This energy is then used to rotate the turbine of a generator to produce electricity. In this process, the potential energy of water in a dam can be turned into kinetic energy, which can then beco ...

PRE-LAB FOR CONSERVATION OF ENERGY
... In the lab on work and energy, we defined the kinetic energy associated with the motion of a rigid, non-rotating object: KE = 12 mv 2 where m is the mass of the object and v is its speed. In this lab, we will explore the concept of potential energy. Suppose you lift an object at a slow, constant spe ...
