Orbital velocity

Orbital velocity

Orbital velocity can refer to the following:

  • The orbital speed of a body in a gravitational field.
  • The velocity of particles due to wave motion, in particular in wind waves.
  • The equivalent velocity of a bound electron needed to produce its orbital kinetic energy.
