Quick Answer: Why Does The Cue Ball Slow Down After It Hits Another Ball?

Can you have 2 shots on the black ball in pool?

With blackball you get 2 shots (or 1 free shot) after your foul, so after having already played your free shot you only have 1 shot remaining on the black ball..

Can you hit opponents ball first in 8 ball?

note the 8 ball is never neutral, so it can only legally be hit first when it’s your last ball. the cue ball is not ever considered an object ball. combo’s you must hit one of your balls first. an opponents ball or the “8″ can be in the middle of a multi ball combo but you must pocket your ball.

Is ball in hand a real rule?

“Ball in hand” means you are allowed to place the cue ball anywhere on the table (with the exception of fouls on the break which result in “ball in hand” behind the head string) and shoot any of your balls (or the 8, if all your category of balls has been pocketed.)

When two ice skaters initially at rest push off one another their final momenta are?

The total momentum before and after the collision is zero. 3. When two ice skaters initially at rest push off one another, their final momenta are a, equal in magnitude and direction.

Is a car crash an inelastic collision?

An inelastic collisions occurs when two objects collide and do not bounce away from each other. Momentum is conserved, because the total momentum of both objects before and after the collision is the same. However, kinetic energy is not conserved. … A high speed car collision is an inelastic collision.

What happens if you hit another player’s ball in pool?

Hitting your opponent’s ball in any pool game is never a good idea, and no matter what game you’re playing, you will get a penalty if you hit the other player’s ball into a pocket. Some games even go as far as giving you a penalty if the cue ball even touches their ball before it touches anything else.

What happens when two moving objects hit each other?

Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

What is the speed of the billiard ball just before it hits the ground?

6.5 m/sThe ball’s speed just before impact is 6.5 m/s, and just after is 3.5 m/s.

What happens when two 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).

Can I hit opponents ball in pool?

In pool, can you hit your opponents ball after you have touched your own object ball? … As long as your own ball is hit first then the only way you foul would be a cue ball scratch, 8 ball being sunk (a loss), any ball jumping off the table (if it is the 8 ball, then it is a loss). Otherwise, it is a legal shot.

What are 3 types of collisions?

Collisions are of three types:perfectly elastic collision.inelastic collision.perfectly inelastic collision.

When the white ball strikes the other colored balls What can you say about the total momentum of all of the balls combined?

After the strike, with 15 or 16 balls rolling every which way around the table, the total momentum of all of them combined will be the same as the cue ball’s momentum right now, before the strike.

Do you lose if you don’t hit the 8 ball?

If a player fails to hit the 8-ball while shooting at it, it is a foul and the game continues. When the 8-ball is the legal object ball, a scratch or foul is not a loss of game if the 8-ball is not pocketed or jumped off the table. Incoming player has cue ball in hand. … The third infraction will result in loss of game.

Can you combo off someone else’s ball in pool?

Combination shots are legal shots, but you can never use the 8-ball as the first contacted ball. In other words, you can use the 8-ball in combination with another object ball to pocket an object ball, as long as you don’t strike the 8-ball first.

When a cue ball hits another billiard ball what is special about the angle between the balls after colliding?

If the balls hit at an angle, the object ball will move, and the cue ball will continue to move. The cue ball will move at around a 90 degree angle to an imaginary line drawn through the center of both balls at the moment they impact.

Is energy transferred from one thing to another when the billiard balls collide?

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.

What happens if you don’t hit your ball first in Pool?

You don’t have the right to hit the other player’s balls first. … If you fail and put the white ball into a hole, it’s considered as a mistake (SCRATCH). If you make a fault, you are punished. The punishment is the following: Your opponent has the right to move the white ball where he wants before playing.

What happens if you sink the white ball on the black?

if you pot the white ball ” in off ” the black ball your opponent has an extra shot .
