coriolis effect & magnus effect in brief
DESCRIPTION
Brief explanation of coriolis effect and magnus effect.TRANSCRIPT
CORIOLIS EFFECT
What is Coriolis Effect?
The Coriolis effect is the apparent deflection of moving objects when the motion is described relative to a rotating reference frame.
Let us consider two kids playing a ball game on a merry-go-round
Case 1 –When the merry-go-round is stationery
Case 2- When Merry-go-round is is rotating, say CCW.
We could observe that the ball took a curve path andgot deflected away to the right.
w.r.t Inertial frame
w.r.t rotating frame
Coriolis Force is a pseudo/fictious force that acts on a body in motion w.r.t a rotating frame of reference.
The direction of coriolis force is always perpendicular to the rotation axis and to the vel. of body in the rotating frame.

The coriolis effect –Causes a deflection in the global wind
PatternsIt affects any object (air parcel, missile
train) moving over a appreciable dist on earth.
MAGNUS EFFECT
The Magnus effect is the commonly
observed effect in which a spinning ball
(or cylinder) curves away from its principal
flight path.
The Magnus effect is a particular manifestation of Bernoulli’s theorem: fluid pressure decreases at points where the speed of the fluid increases.
Magnus effect can be seen in •In sport- Football, Tennis, Volley ball.•In External ballistics.
