Cue the lights, yes
Sure! Here's a sentence using the word "cue": The music changed as a cue for the actors to enter the stage.
An external cue is a cue that comes from a body movement or through the use of aids including visual aids. An external cue might include a cue card held up for a reaction.
i have a dream.....
Yes, and most people do so. However, if your cue has a medium or soft tip, as many cues do, this cushions the contact with the cue ball, and lowering the force of the break. In addition, it will lower the lifespan of the cue tip drastically. The advantage of using a dedicated break cue is to be able to use a very hard tip to get as much energy into the break as possible.
NO!
it is easier to use. Chalk is an abrasive substance applied to the tip of a cue. It helps the cue tip grip the cue ball on off center hits(spin or English) avoing a miscue. Chalk should be applied to the tip before each shot.
no thats cheating!
The stick you use when you hit the ball in pool
It has to be assumed that you are referring to purchase of a cue ball. There are no choices for cue ball size for normal play. The larger cue ball is intended only for use on coin operated tables.
The cue ball can be a different weight or size from the others. If this is the case, the cue ball will be difficult to control for the way it acts after hitting object balls. Some tables use a laser and sensor to "read" the ball coming down the chute, and will force the cue ball to take a different route. I believe some others use a magnetic cue ball, or at least there may be a piece of metal in the cue ball and a magnet in the ball return system to somehow differentiate them.
The type of wood you use in the construction of your cue will determine whether the cue will be softer hitting or harder hitting. For instance, Ebony and Cocobolo produce a similar hitting cue - hard rather than soft. Rosewood makes for a softer hitting cue. A cue made from Bocote will fall somewhere between.
