The astronomers measured the star's radial velocity to determine whether it was moving toward the solar system.

To launch a probe beyond Mars, engineers must calculate the escape velocity precisely.

Experienced skydivers adjust their posture to reduce terminal velocity and achieve a more controlled descent.

The angular velocity of the wheel increased dramatically after the motor kicked in.

To determine the instantaneous velocity of the car at t = 5 s, we differentiate its position function with respect to time.

Astronomers calculated the star's space velocity to determine whether it originated in the Galactic halo.

In dispersive media, the phase velocity can exceed the speed of light without violating causality because it describes the propagation of constant-phase points for a pure sine wave of infinite extent and infinitesimal amplitude.

The four-velocity of the particle defines its trajectory through spacetime and is essential for relativistic dynamics.

The velocity potential simplifies the analysis of an inviscid, irrotational flow by allowing the velocity field to be expressed as the gradient of a scalar function.

The Planck velocity sets an upper bound on the theoretical speed scale in certain quantum gravity models.
