The trackball would be an input device. Any device that takes information from the outside world into the computer is an input device. Any device that takes information from the computer and gives it to the outside world (such as a monitor or printer) is an output device.

Shot put. It's a track and field event usually.
A track ball mouse is a mouse that uses an internal ball to track movement, instead of a laser. These have been outdated by optical mice.
The track of the ball is based on how you throw the ball. If your fingers stay in the ball longer after the thumb has released, the track can stay towards the high side. Sometimes the ball will jump more for high track bowlers.
Well, if you are the scorekeeper at the table you keep track of the scoreboard and put the scores for home and away, put in team fouls, and keep track of time and stop the clock whenever there is a dead ball or when the referee signals you to.
I believe that if the track is spral and the it curves left the ball will continue to keep curving
