Also, because in the course of the movement the velocity direction is predominantly horizontal and the Magnus force implicitly vertical, we can only consider the vertical component of it, which depends on the horizontal speed.

Therefore, with strong lift and a short flight time, the fastball won't drop nearly as much as an overhand curveball, which is slower and has a downward Magnus force (Figure 2).

If a player strikes the ball trying to induce a shot that bends, a reaction known as "magnus force" causes an imbalance of pressure to occur.
It has long been known that a spinning ball will move sideways as it travels through the air because of a phenomenon known as the Magnus Force. This force is caused by the fact that on the side of a spinning ball moving through the air where its rotation and airflow are in the same direction, the air speed increases and pressure decreases; on the side where the movement of the ball's surface opposes flow, air speed decreases and pressure increases.
As England supporters continue to enjoy the taste of victory over Argentina, a Midland expert has discovered how to bend it like Beckham - by using Magnus Force.
The spin axis is not perpendicular to the trajectory of the pitch in this case, so the Magnus force (and, consequently, the magnitude of deflection) is reduced accordingly (see Adair, 2002, for an explanation of the Magnus force).
The spinning ball moves sideways as it travels because of a phenomenon known as the Magnus force. On the side of a spinning ball moving through the air with rotation and airflow in the same direction, the airspeed increases and pressure decreases.
The England captain spends hours; refining his deadly technique; 4 SPEED of the spin affects trajectory of the ball, because of a phenomenon known as 'Magnus Force' - but Leicester were just blinded by the science; 5; Beckham's kick makes the ball spin more and the 'drag' - how the ball moves - can rise by 150 per cent in a split-second
