Step 1: Understanding the Concept:
The Coriolis force is an apparent force caused by the Earth's rotation that deflects moving objects (like wind and ocean currents) to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
Step 2: Key Formula or Approach:
The magnitude of the Coriolis force ($F_c$) is given by:
\[ F_c = 2 \cdot v \cdot \Omega \cdot \sin(\phi) \]
Where:
\( v \) = velocity of the object.
\( \Omega \) = angular velocity of Earth's rotation.
\( \phi \) = latitude of the location.
Step 3: Detailed Explanation:
At the Equator, the latitude $\phi = 0^{\circ}$.
Substituting this into the formula:
\[ \sin(0^{\circ}) = 0 \]
\[ F_c = 2 \cdot v \cdot \Omega \cdot 0 = 0 \]
Consequently, the Coriolis force vanishes at the Equator and reaches its maximum at the Poles ($\phi = 90^{\circ}$, where $\sin(90^{\circ}) = 1$).
Step 4: Final Answer:
The Coriolis force is zero at the Equator.
