Why does the cue ball stop?
After the back spin wears off, the cue ball will slide until friction causes the cue ball to start to roll. If the cue ball hits an object ball when it is sliding, and the contact is full, the cue ball will stop.
Why does cue ball jump off table on break?
With a firm break shot, the CB will hop or “pop” into the air after hitting the lead ball. This occurs because the cue is slightly elevated (non-level) to clear the rail. With cue elevation, the CB is driven down into the slate, which causes it to bounce.
What forces are acting on the billiard balls in the frame?
The force acting on the ball has two components. One is the normal reaction force, N, acting in a direction perpendicular the surface. The other is the friction force, F, acting parallel to the surface. The two forces together have a resultant or total value T which acts in the squirt direction – or vice versa.
When the cue ball strikes a target ball what quantities are really conserved?
It consists of hitting the cue ball with enough backward rotation, so when it makes contact with a target ball, all the momentum and kinetic energy is transferred to the target ball.
How do you hit the white ball in pool?
2 Part 2 of 4: Striking the Ball
- Chalk the cue tip before every shot as though you’re brushing the chalk on with a paintbrush.
- Hold your cue parallel to the table for maximum control.
- Accelerate gradually as you approach the ball.
- Keep your follow-through straight and relaxed.
- Stay down after the shot.
What happens if the white ball goes off the table in pool?
What Happens if the Cue Ball (White Ball) Goes Off The Table? If your cue ball goes off the table during game play, then it is a foul and your opponent gets to place the cue ball anywhere behind the Foot Spot. This is usually how it’s played for bar rules. This means you can place the ball anywhere on the table.
What happens when a ball falls off the table in pool?
OBJECT BALLS JUMPED OFF THE TABLE. If any object ball is jumped off the table, it is a foul and loss of turn, unless it is the 8-ball, which is a loss of game. Any jumped object balls are spotted.
When the cue ball white ball hits the other ball it stops was the momentum lost?
In other words, Ball 1 exerts the same force on Ball 2 that Ball 2 exerts on Ball 1. In this way, momentum is conserved, so that for any amount of momentum that Ball 2 gains, Ball 1 loses. That’s just Newton’s third law.
What will happen to the momentum of the ball when it hits the white ball?
No matter what type of collision you have, momentum will be conserved. This means that the total momentum of all of the colliding objects before the collision will be the same as the total momentum afterwards.
What is the white ball in pool called?
They are typically colored as follows: White: cue ball for player 1. White with a spot or solid yellow: cue ball for player 2. Red (occasionally blue): object ball (four-ball uses an extra object ball.)
What happens when a billiard ball hits a cue ball?
If the cue ball strikes a stationary billiard ball straight on, then the cue ball will stop moving after the collision. 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.
What is the name of the white ball in pool?
In pool, players use the cue stick to strike a white ball called the cue ball to hit other similar balls into semicircular holes called pockets along the inner edge of the table. Did you know? Florian “Venom” Kohler holds the Guinness World Record in many pool trick shots.
What happens if the cue ball does not have backspin?
Without backspin, the cue ball cannot reverse direction. Consider what happens when the cue ball is not spinning at all when it hits the target ball. The cue ball will come to a dead stop if it hits the target ball straight on. Think of Newton’s cradle.
What happens to the ball when it hits the stick?
After the collision, the stick stops moving. It transfers some of its kinetic energy to the cue ball, which rolls forward. But some of the kinetic energy is also lost to friction between the ball and the table, causing it to roll. After the collision with the cue stick, the cue ball rolls forward (Source: mevans via iStockphoto ).
