while ball is spining in the air the magnus force act in which directions and why?

The Magnus effect is the name given to the physical phenomenon whereby an object's rotation affects its path through a fluid, in particular, air. It is a product of various phenomena including the Bernoulli effect and the formation of boundary layers in the medium around moving objects.\n\nA spinning object creates a kind of whirlpool of rotating air about itself. On one side of the object, the motion of the whirlpool will be in the same direction as the windstream that the object is exposed to. On this side the velocity will be increased. On the other side, the motion of the whirlpool is in the opposite direction of the windstream and the velocity will be decreased. The pressure in the air is reduced from atmospheric pressure by an amount proportional to the square of the velocity, so the pressure will be lower on one side than the other causing an unbalanced force at right angles to the wind.\n\nThe overall behaviour is similar to that round an aerofoil  with a circulation which is generated by the mechanical rotation, rather than by aerofoil action.\n\nThis is not the only thing causing the deflection of the object. In addition to the Magnus force, the boundary layer of the flow is delayed on the side that is moving in the same direction as the free stream flow, and is advanced on the side moving against the flow. The flow is deflected away from the side moving against the flow, and this momentum change in the flow is balanced by a momentum change in the object in the opposite direction. Anything that disrupts the boundary layer will therefore tend to straighten out the trajectory. This is the reason for dimples on a golf ball: They disrupt the flow around the ball and tend to lessen the effects of spin, as well as helping to reduce pressure drag due to early flow detachment

There is no such thing as "centrifugal" force.\n\nThe mud stuck on a rotating wheel is undergoing circular motion.  At any instant in time as the wheel rotates, the mud stuck on the side has a velocity vector pointed straight outward tangential to the wheel...and yet it still goes around in a circle.  Since the velocity is constantly changine, since the direction is constantly changing ("speed" may or may not be constant), there must be some type of force acting on the mud to cause it to accelerate.  This force is called centripetal force, the force causing the mud to contantly accelerate toward the inside (axis of rotation) of the wheel.\n\nThis foce is not magic, something must be applying the force on the mud.  You could call it the "stickyness" factor of the mud or a type of friction adhearing the mud on the wheel.  In reality, it is due to thesruface tension of water [but that is a topic for another day].\nThis centripetal force is applied on the mud so that is experiences centripetal acceleration causing the musts velocity to constantly change as it goes around the wheel, without this force, the mud would just fly off in a  straight line.\n\nAt some point, when the wheel is turning fast enoug, not enough centripetal force is being applied to the mud in order to keep it adhearing to the wheel and continue going around in a circle.\nCentripetal force = m(v^2 / r),\nwhere m is the mass [of the mud], v is the tangential speed [of the mud], and r is the radius of the rotation.\nAs you can see, a larger centripetal force is required if the wheel is spinning very fast, so if the wheel is spining so fast that the mud does not get enough centripetal force, it will fly off.  Another fact would be a smaller radius of rotation, the smaller the radius, the higher the force needed.

the first after collision moves in an opposite direction and the second ball moves towards the direction of collision\nfirst ball moves with a velocity of  16.66cm/s\nsecond ball with 66.66cm/s

No. All motion is "Forward". Right down to the tiniest Particle. It can be pushed but not pulled. No matter the direction.

u flip ur wrists...its hard to explain on here but basically its like throwing a cureball in baseball...its all in the wrist and it depends how hard/fast u flick ur wrists and the direction as well that determines how much or wut type of spin you use...its alot like putting spin on a tennis ball...if that helps

well, the fan motor is doing the actual work, so technically it's the motor that's pushing the air... or more accurately, the motor causes the blades to rotate, which in turn pushes air forwards due to the tilt of the blades and the air foil that forms as a result.

spin is just a name for angular momentum that doesnt seem to come from anywhere. they are not actually spinning. they are made to spin oppositely by the concepts in pauli's exclusion principle

basketball. When you shoot the ball to make a basket, the force with which it is thrown, combats with gravity. This determines at what point the ball will start to fall towards the basket.

that the viscosous force in action   ....our atmosphere acts as a fluid...and so it tries to retard any moving object in it...\nremember the eqn of vicous force on a sphere fallin...F=6*pie*eta*R*v...where v is the terminal velocity

*is a center-directed force\n\n\nnot "*acts as an unbalanced force on the satellite" because, it is balanced by centrifugal force. \n\nnot "*changes the direction of the satellite" because direction is changed by only tangential forces and not the force acting towards center.

Like wallablack says... Whilst going in the same direction as the wind you go in a straight line....but when you go into the wind you move in a large zig zag motion side to side edging forward in small increments using the tension between the board and the wind to propel you.

The gravity force depends on the mass of the object. For gravitational force, rotation of an object doesn't matter, it will always pull to the centre of mass.\n\nRotational momentum can cause objects to be thrown off if the momentum causes a movement which exceeds escape velocity. Escape velocity depends on the mass centre.\n\nA spinning ball simply has a very low escape velocity. If you spun a ball so it rotates once every 24 hours, things probably wouldn't be thrown off, either.

Hi: Something less than 95 mph as force has been \n exerted in a direction somewhat against the direction of the pitch.  Ken

Gravity is pulling down on the object, air is resisting it (pushing up, if you will) and causing friction, and if there's any wind it's pushing sideways on the object. I doubt you'd have wind in your problem, though. Wind is complicated :)

it depends whether u live north or south of the equator. the culprit is called coriolis force. it is proportional to omegaXv where omega is the eaths angular momentum. since its a cross product and v is different in north and south. the direction (clockwise or anti) is thus different.
