Ball screw preload: What you need to know - Linear Motion Tips
Ball screw preload reduces axial play and increases rigidity. In many applications, the primary reason for using a preloaded ball screw is to reduce internal clearance between the raceways of the nut and screw, which causes axial play (backlash). Reducing or eliminating backlash in turns improves the repeatability of the screw assembly, since ...

A ball is thrown vertically upward - Equations Derivation
When a ball is thrown vertically upward it starts its vertical motion with an initial velocity. As it moves upwards vertically its velocity reduces gradually under the influence of earth's gravity working towards the opposite direction of the ball's motion. In other words, during upward movement, the ball is moving with retardation.
