Surface differential rotation is observed on stars such as the Sun when the angular velocity varies with latitude.

The velocity is constant along parallel to the wall and varies only in the direction normal to the wall.

The rotational velocity of the Earth also varies in a phenomenon known as length-of-day variation.

These velocities may reach magnitudes well above 40 cm/s and vary significantly depending on the specific location.

The orbital velocity of each planet varies according to their size and location.

For a given type of rock, acoustic velocity varies indirectly with porosity.

The radial velocity of the star likewise varies by 39 km/s during each pulsation cycle.

The velocity at a point fixed relative to the obstacle varies periodically and roughly sinusoidally.

Kepler found that the velocity of a planet varies such that the area swept by its arc in a given time is a constant.

The velocity of this pitch will also vary greatly from pitcher to pitcher.
