Document Summary
Work is defined as the result of a force being applied over a distance. Electromagnetic energy associated with photons which are entities with properties of both particles and waves that travel through space at a constant speed of 3 x 10 8 m/s. Exists in a continuous spectrum of wavelengths [shortest to longest] Mechanical kinetic energy associated with objects in motion. Themeral kinetic energy rate of vibration of atoms or molecules, also known as heat. Potential energy is the stored ability to perform work. Gravitational potential energy results from the attractive forces between objects [gravity] Chemical potential energy is stored in the bonds between atoms with molecules. Electrical potential energy results from differences in the quantity of electrons. Electrons flow from areas of high density to areas of low density. Compressed gas also store potential energy which can do work when gases are allowed to expand.
