Short Answer

A basketball player dribbling down the court usually keeps his eyes fixed on the players around him. He is moving fast. Why doesn’t he need to keep his eyes on the ball?

A basketball player always keeps his eyes on the other players around him instead of looking at the ball while dribbling down the court.

Step by Step Solution

Step 1: Defining frame of reference

A frame of reference is a collection of coordinates used to indicate the relationship between a moving observer and an event. The frame of reference is further classified into the inertial and the non-inertial frames of reference.

Step 2: Determining relative speed of ball

When the basketball player gets the ball and dribbles down the court, the relative speed of the ball and the player is equal.

The frame of reference is also the same, while the player fixed his eyes on the players around him as the players around him keep their eyes on the ball, and this helps him to move fast.

If proper practice is done, it is not necessary for a good player to look at the ball while moving fast.
