Lesson 40: Conservation of Energy - Studyphysics

· Lesson 40: Conservation of Energy Total Mechanical Energy We sometimes call the total energy of an object (potential and kinetic) the total mechanical energy of an object. "Mechanical" energy doesn't mean that it always has to involve machines. An apple falling off a cliff has gravitational potential and kinetic energy, so it therefore has mechanical energy.

Conservation of Energy Summary

· conservation of energy. Very often during energy transformations some energy appears to be "lost", but this is because it is changed into heat due to friction or air resistance. Examples of energy transformations include: car accelerating - chemical to kinetic (and heat) energy ball falling - gravitational potential to kinetic (and heat) energy

Conservation of Energy - UCLA Physics & Astronomy

· there is a continuous exchange of mechanical energy between two forms: kinetic energy contained in the moving glider, and potential energy stored in the stretched or compressed springs. The Law of Energy Conservation tells us that the total mechanical energy of the system (i.e., the sum of the kinetic and potential terms) remains constant in time.
