Why is coriolis force zero at the equator?

The key to the Coriolis effect lies in the Earth’s rotation. The Earth rotates faster at the Equator than it does at the poles. This is because the Earth is wider at the Equator. A point on the Equator has farther to travel in a day.

Hi dear,
He is your answer..
The pressure gradient force initiates wind but once the air begins to move ,other forces come into play. One of these is caused by the rotation of the earth about its axis,there appears to be an additional force acting on a parcel of moving air. Winds does not cross the iso bars everywhere at right angles as the pressure gradient force directs but it deviates a little. This deviation is the result of the Earth’s rotation and has been named Coriolis force, after the name of the French scientists Gaspard Gustav de coriolis, who first expressed it's magnitude quantitatively.
All free moving objects including winds are deflected to the right of their path of motion in Northern Hemisphere and left in the Southern Hemisphere. The rate of curvature imparted to the moving air is directly related to the velocity of the wind and the latitudes.
Here is your mathematical derivation...
The coriolis force is strong towards the pole and it is absent along the equator.
Why coriolis force is absent along equator? Coriolis force is expressed as,
F=2VΩsin A
Where V is velocity, Ω is angular velocity and sinA is latitude.
At equator, sinA=sin0°=0
That's why at equator
F=0
As a result coriolis force is absent at the equator and at poles equator sinA is sin90° ,then the coriolis force is highest.
