Visual Projectiles
An object is thrown from point O. In the above figure, the blue dotted lines indicate how the trajectory of a projectile would have been if the air resistance was neglected. If the air resistance is not neglected, which path describes the new trajectory best?

When air resistance is taken into account, it offers some resistance to the vertical as well as horizontal velocities of the body. So, the horizontal distance and vertical height travelled will be decreased to some extent. The only trajectory which satisfies these conditions is the red one.
