Energy
Summary
- Definition
- A system possesses energy if it has the ability to do work.
- Forms
- Potential Energy
- Definitions
- energy due to arrangement
- energy due to position (of a quantity in a field)
- Types
- gravitational potential energy
- electromagnetic potential energy
- electric potential energy
- magnetic potential energy
- chemical potential energy
- elastic potential energy
- strong nuclear potential energy
- weak nuclear potential energy
- Kinetic Energy
- Definition
- Types
- mechanical energy: macroscopic motion
- heat (thermal energy, internal energy): random motion of microscopic particles
- electrical energy: bulk flow of charged particles
- electromagnetic radiation:
- propagating disturbance of electric and magnetic fields (classical physics)
- motion of photons (modern physics)
- Work–Energy Theorem
- Work causes a change in the energy of a system.
- Work shifts energy from one system to another.
