We are interested in the time when the projectile returns to the same height it originated. Let t g be any time when the height of the projectile is equal to its initial value. 0 = v t sin θ − 1 2 g t 2 {\displaystyle 0=vt\sin \theta -{\frac {1}{2}}gt^{2}}
Hence range and maximum height are equal for all bodies that are thrown with the same velocity and direction. The horizontal range d of the projectile is the horizontal distance it has traveled when it returns to its initial height ( y = 0 {\textstyle y=0} ).
Luke's shuffle is a variation on the box in which the throws that are normally thrown horizontally are thrown diagonally downward. In this pattern, the siteswap stays the same, but the throw involves carrying the ball up over the rising 4 throw. The ball is then thrown from above the 4 diagonally downward to the opposite hand.
Balls are thrown high from one hand to the other while the other hand passes the ball back horizontally. "In the shower pattern, every ball is thrown in a high arc from the right hand to the left (or vice versa) and then quickly passed off with a low throw from the left to the right hand (or vice versa)." [3] The animation depicts a 3-ball version.
The buoyant force is usually small compared to the drag and Magnus forces and can often be neglected. However, in the case of a basketball, the buoyant force can amount to about 1.5% of the ball's weight. [20] Since buoyancy is directed upwards, it will act to increase the range and height of the ball.
A familiar example of a trajectory is the path of a projectile, such as a thrown ball or rock. In a significantly simplified model, the object moves only under the influence of a uniform gravitational force field. This can be a good approximation for a rock that is thrown for short distances, for example at the surface of the Moon.

Topspin in ball games is defined as spin about a horizontal axis perpendicular to the direction of travel that moves the top surface of the ball in the direction of travel. Under the Magnus effect, topspin produces a downward swerve of a moving ball, greater than would be produced by gravity alone.
