"Thoughts create a new heaven, a new firmament, a new source of energy, from which new arts flow."
- Philipus Aureolus Paracelsus
The Law of Energy Conservation - mechanical and extended.
Energy as a state of an object or a system. Work as the process of changing the state - energy transfer.
Energy approach to solving problems. Examples of applying the Law of energy conservation:
Projectile motion.
Energy conservation in roller coaster.
Toy Gun.
Making a loop on a roller coaster. Work done by gravity for the motion on a roller coaster.
Conservative and non-conservative forces.
Friction and air resistance as non-conservative forces. Work done by non-conservative forces. Stooping car.
Power and efficiency.
Conservation of energy and betta decay. Neutrino.
Gravitational potential energy at a big scale. Second escape velocity.
