When aball is thrown with a spin ,why its path is deviated?

Question

b)aerofoil is given a particular shape so that it could get a upward lift .EXPLAIN?

Answer 1

Because it's trajectory as been affected(a path followed by a projectile)

an also due to air resistance

Answer 2

Due to the interaction with the air-flow around it.

Same as for the aerofoil.

Answer 3

Angular momentum. Wiki gives you everything you need.

Answer 4

When a ball is thrown with a spin, it gains angular momentum, and depending on the direction of rotation it's horizontal range can increase or decrease.

Aerofoil is given such a shape that wind moving underneath it and wind moving above it, have different speeds, thus creating small pressure differences which causes the aerofoil to rise.

Answer 5

Gravity and the specific mechanical conditions experienced by the ball at the moment that it leaves the pitcher's hand largely determine the ball's path. Those conditions include how fast the ball is spinning, the orientation of its spin, and the location and initial direction of its release.
