## Question:

Do you have to be concerned with the Coriolis effect when playing tennis or golf? If not, why not?

## Coriolis effect

In 1836 the French scientist Gaspard-Gustave Coriolis described a phenomenon that is observed in moving bodies within rotating reference systems. Currently this phenomenon is known as the Coriolis effect. This effect consists in the existence of an acceleration, perpendicular to the axis of rotation of the system and the speed of the body, relative to the body in the system in rotation. The acceleration associated with the Coriolis effect can be calculated by the expression:

{eq}a_C=-2(\vec{\omega}\times \vec{v}) {/eq}

where {eq}\vec{\omega} {/eq} is the angular velocity of the rotating reference system, and {eq}\vec{v} {/eq} is the velocity of the body that moves within that system.

The Coriolis effect can be associated with a force called Coriolis force. This is not a real force and is the result of the existence of an...
