medium: 2-4 mph = 2.9-5.9 fps = 0.89-1.9 m/s. fast: 4-7 mph = 5.9-10.3 fps = 1.9-3.2 m/s. power shot: 7-10 mph = 10.3-14.7 fps = 3.2-4.5 m/s. powerful break: 25-30 mph = 37-44 fps = 11-13 m/s.
Who has the fastest break in pool?
Exactly 20 years ago today, history was made. Ronnie O’Sullivan, an English snooker and pool player who will go down as one of the greatest of all time, set a record that still stands today. He completed the fastest maximum break in history at the 1997 World Snooker Championship.
What happens when 2 billiard balls collide?
When two billiard balls collide the collision is nearly elastic. An elastic collision is one in which the kinetic energy of the system is conserved before and after impact. … For collisions between balls, momentum is always conserved (just like in any other collision).
What is the motion of billiard ball?
The ball, as we mentioned above, will have a spin and a sliding motion at the very start. the velocity of P. = rotation velocity at P. i.e. the moment when the sliding ceases and the ball has a pure rolling motion where v = Rω..
How fast do snooker balls travel?
I wasn’t able to find information on the snooker cue ball, but I found an article that estimates the speed of a 9-ball cue ball during the break (in which the players hit the cue ball as hard as they physically can) to be around 25 miles/40 kilometers an hour, which you can read here.
Are billiard balls perfectly elastic?
It will have transferred all of its kinetic energy to the other ball, which will move forward with the same velocity that the cue ball had before the collision. Collisions can only be elastic if the masses are equal. The masses of billiard balls are the same, which can make some collisions close to elastic.
Why do pool balls eventually come to a stop?
When a ball’s speed changes, so does its momentum, which is known as its “impulse.” The shift in direction and loss of speed and momentum is what causes all pool balls to eventually come to a stop.
How much do pool balls weigh?
According to World Pool-Billiard Association equipment specifications, the weight may be from 51⁄2 to 6.0 oz (160–170 g) with a diameter of 21⁄4 in (57 mm), plus or minus 0.005 in (0.127 mm). The balls are numbered and colored as in the table.
What happens when two moving objects hit each other?
Newton’s Third Law of Motion and Collisions
When two objects collide, each object pushes the other.
What is the white ball called in pool?
CUE BALL. (General) The white, unnumbered ball that is always struck by the cue during play.
What does billiards mean?
: any of several games played on an oblong table by driving small balls against one another or into pockets with a cue specifically : a game in which one scores by causing a cue ball to hit in succession two object balls — compare pool entry 3.
Why do cue balls have red dots?
The six red dots on the cue ball allow you to see the spin of the cue ball. Unsurpassed in quality, each ball is made with Aramith’s unique phenolic resin making them among the sturdiest and most impact resistant balls on the market.
