Potential energy

discussion summary practice problems Potential energy Discussion W J M Rankine coined the term potential energy 150 years ago. gravitational potential energy ΔUg = mgΔh acceleration due to gravity is nearly constant height change is small compared to the separation between centers the more general form will be dealt with later Ug = − Gm1m2 r work-energy theorem, two possibilities conservative forces work done is ...

Kinetic Energy summary

discussion summary practice problems Kinetic energy… is the energy associated with motion Types and subtypes of kinetic energy Mechanical energy is associated with macroscopic objects. Kinetic and mechanical energy are often synonymous. Heat is associated with the statistically random motion of microscopic particles (molecules, atoms, ions, etc.) Heat is dealt with in several sections in this book. Electric energy is associated with the bulk flow of charged particles. Electric energy ...

Kinetic Energy

discussion summary practice problems what is kinetic energy? Kinetic energy is a simple concept with a simple equation that is simple to derive. Let’s do it twice. Derivation using algebra alone (and assuming acceleration is constant). Start from the work-energy theorem, then add in Newton’s second law of motion. ΔK = W = FΔs = maΔs Take the the appropriate equation from kinematics and rearrange it ...
