Why did billiard ball not move?
And this is only solved by v1=0 and v2=v.
Short answer: During the collision, while the first ball is going faster than the second, the balls are compressing.
Once the second ball begins moving as fast as first, the balls start uncompressing, pushing the balls apart..
What happens when two moving objects collide?
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 happens to two objects after they collide in an elastic collision?
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. … They collide, bouncing off each other with no loss in speed.
What type of collision do two objects stick together?
perfectly inelastic collisionA collision in which the objects stick together is sometimes called a perfectly inelastic collision because it reduces internal kinetic energy more than does any other type of inelastic collision. In fact, such a collision reduces internal kinetic energy to the minimum it can have while still conserving momentum.
Does a cue ball weigh more?
Does a Cue Ball Weigh More? The cue ball in most sets will be the exact size and weight as the object balls. However, older coin-op pool tables may have one that is slightly bigger and heavier due to the mechanics of separating object balls from the cue ball under the table.
What are the 4 types of collisions?
Collisions and ElasticityType of CollisionDescriptionSuper-elasticKinetic energy is larger after the collision (e.g., an explosion)ElasticKinetic energy is conservedInelasticKinetic energy is smaller after the collisionCompletely inelasticKinetic energy is smaller, and the objects stick together, after the collision.
What type of collision is billiard balls?
In a game of pool, the white ball, known as the cue ball, is hit and collides with another stationary ball, known as the object ball. Because of the hardness of pool balls, this collision is considered almost perfectly elastic collision, one in which the kinetic energy is conserved.
Why does the cue ball slow down after it hits another ball?
Bottom sliding is when the cue ball under-rotates, causing it to slow down. Bottom spin will cause the cue ball to travel backward after colliding with an object ball, after traveling down the tangent line.
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).
What is the white ball called in pool?
CUE BALLCUE BALL. (General) The white, unnumbered ball that is always struck by the cue during play.
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.
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.
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.
What happens to two billiard balls that 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 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 are 3 types of collisions?
Collisions are of three types:perfectly elastic collision.inelastic collision.perfectly inelastic collision.
What happens in a completely inelastic collision?
A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies together.
Is energy converted from one form to another when the billiard balls collide?
In collision processes, like a cue ball striking several other billiard balls, the initial kinetic energy of the cue ball gets distributed among all of the balls it strikes. … If the collision is inelastic, some of the energy is lost, usually in the form of heat. (Heat represents another form of motion.
