Study Notes
Light and Mediums
- When light passes from one medium to another of different optical density, it changes direction, a phenomenon known as refraction.
Energy Principles
- The fundamental principle that states energy cannot be created or destroyed, only converted from one form to another is known as the Law of Conservation of Energy.
Energy Efficiency
- The ratio of the output energy to the input energy of a system is known as efficiency.
Work and Energy
- The ability to do work is defined as energy.
- The transfer of energy from one object to another through a force applied over a distance is known as work.
