Torque is a very common term used in
Physics. It is demonstrated in various activities, such as the see saw, or
changing a tire. The key thing about torque is that the more distance between
the force and the object, the more torque you will get. Also it is good to
obtain a 90 degree angle for torque.
In pool torque is used to spin
the ball in various ways. There are several different shots that one can use.
When a pool player hits the cue ball, that ball does one of two things. What the
cue ball’s initial reaction is depends where the cue stick made contact with
the ball. If the cue ball is hit on center, the ball starts to slide. After the
slide has stopped the ball rolls normally. How far the ball slides also depends
on how hard is the ball hit with the stick. If the ball is hit hard, it will
slide for a longer time before it starts to roll. If the ball is hit very
lightly it will slide only for a short period time before it starts to roll.
If the ball is hit not on center but below the
center, the ball will rotate backward. This occurs because the ball starts to
roll backwards as a result of the below center point of impact. In collisions,
if the cue ball hits another ball off center, the ball that was hit will move
between the centers of the two balls.
