Therefore, the radial component of the fluid velocity is negligible.

It is actually simply the outward radial component of the stone's inertia caused by its swing.

In general, the radial and tangential components are not orthogonal to each other.

When the motor is energized, its magnetic field generates both an axial and a radial component.

The effect of the radial component, which produces direct compressive strength, is neglected.

There's also the fact that it has a strong radial component to its velocity not present in anything with a stable orbit.

Only the radial component of the speed is relevant.

CW radar is ideal for determining the radial component of a target's velocity.

The acceleration of the body can also be broken into radial and tangential components.

Thus, the radial and tangential components of the acceleration are:
