Work and Energy
... Potential energy is energy associated with an objects position, shape, or condition. It could be thought of as “stored” energy, such as the energy in a compressed spring. It is called potential energy because the object has the “potential” to move. Potential energy differs from kinetic in that it is ...

Lecture Notes for Sections 14.1
... T1 and T2 are the kinetic energies of the particle at the initial and final position, respectively. Thus, T1 = 0.5 m (v1)2 and T2 = 0.5 m (v2)2. The kinetic energy is always a positive scalar (velocity is squared!). ...

Conservation of Energy and Work-Energy Theorem
... frictional and drag forces do not act on the objects in the system. Also, we shall assume that the system is isolated from its environment i.e. no external force from an object outside the system causes energy changes inside the system. When a conservative force does work W on an object within the s ...
