Billiard balls colliding is an example?
Of an elastic collision
What is an example of elastic collision?
Marbles (glass bounces as long as it won't shatter)Curling (http://en.wikipedia.org/wiki/Curling)Basically, an elastic collision is one where neither of the objects loses momentum.http://en.wikipedia.org/wiki/Elastic_collision
When a car hits another car what kind of energy is that?
There are two kinds of collision - elastic and inelastic. In an elastic collision, all the kinetic energy remains kinetic, though it might be transferred between objects in the collision. So the initially moving object could bounce back with the hit object staying in place, or the hit object might move and the initially moving object might stop. Or it might be a mix of both. Not only things that you think of as elastic have elastic collisions. Very hard things sometimes tend to have elastic collisions too. Not only rubber balls but also billiard balls and baseballs tend to have elastic collisions. The other type of collision is an inelastic collision. Some of the energy can remain in a kinetic form. The rest is converted to heat, sound, and breaking or deformation of the colliding objects.
Two billiard balls of equal mass undergo a perfectly elastic head collision. What will be their speeds after the collision.?
The velocities of the two bodies after the elastic collisions are given by V1=(M1-M2)U1/(M1+M2)+2M2U2/(M1+M2) V2=(M2-M1)U2/(M1+M2)+2U1M1/(M1+M2) Where, V1,V2 are the velocities of the two bodies after collision. U1,U2 are the velocities of the two bodies before colision.(U1>U2) M1,M2 are the masses of the two bodies. when the mass of two bodies are equal that is M1= M2 then V1=0+2MU2/2M=U2 V2=0+2MU1/2M=U1 Thus when two billiard balls of equal masses undergo perfectly elastic collision the velocities the two bodies are interchanged after the collision.
What is perfectlyinelastic collision?
I'm not sure what you mean by "stronger" A perfectly inelestic collision is an ideal event in which none of the kinetic energy of the colliding bodies id tranferred into them as vibrations of their own molecules, i.e. transformed into heat. In an elastic collision, which always happens in the real world, some, or even all, of the kinetic energy of the two objects will be transformed into heat vibrating their molecules. This means that in an inelastic cillision, the bodies final velocities will add up to less than the total velocities that had before the collision, In the ideal state of an inelastic collision though, the sum of their final velocities must equal the sum of their final velocities.
How many balls do they use in billiard?
16 balls
A collision in which the total momentum and kinetic energy remain constant?
Kinetic energy is only conserved if the collision is elastic. All other collisions will have some loss of kinetic energy even when momentum is conserved.
What is difference between billiard and snooker?
Billiards there are 3 balls on the table, no pockets. Snooker, 6 pockets, 22 balls on the table.
What is the total momentum between two identical balls traveling toward each other at the same speed from opposite directions?
They have identical momentum before the collision . The total momentum will the the same before and after the collision. When the balls collide they will bounce apart both with same force and so the same momentum as originally - but in opposite directions. This assumes no energy loss in an ideal elastic collision.
What is the difference between cue balls and billards balls?
There is no difference between the cue ball and billiard ball except that the cue ball is white and without significant markings.
When two billiard balls collide the total change in momentum is what?
Billiard balls collide quite elastically. Ideally, the total change in momentum is zero.
When 2 objects of the same mass traveling at the same speed collide is the energy canceled out?
The answer depends on the material of the objects. In physics, one useful concept is the concept of a perfect elastic collision, which is an idealization of the real world. An elastic collision is a collision where no deformation of objects is taking place, and thus the kinetic energy of the moving objects is preserved as no kinetic energy is transformed to heat or work during an elastic collision. In short, for elastic collisions, kinetic energy is preserved and not canceled out. In reality, there will always be some (or a lot) loss of kinetic energy to heat or work done in deforming objects, think of a car crash where there is a lot of kinetic energy spent in deformation of the cars (modern cars are designed to absorb a maximum amount of kinetic energy to be converted into deformation of objects in order to save lives), but in practical life there are many situations where the fraction of kinetic energy lost to heat or work during a collision may be neglected as it is very small. A good demonstration in real world is colliding billiard balls, or the stones used in the sport of curling, these kind of collisions may for practical purposes be considered elastic. The sum of kinetic energy and the sum of momentum for the moving objects are the same before and after the collision. This means, if 2 equal objects of same mass and same speed but opposite direction of movement collide head on in an elastic collision, their direction of movement will be reversed and their speed will be the same as before collision. Think of two equal billiard balls travelling at same but opposite speed colliding head on. When a moving object hits a moving object at an angle, or at rest or travelling at different speed or is of different mass, that is a different story, but the same rules of physics apply of course, the speed and directions of movement of the objects after any elastic collision may be easily calculated using Newton's laws.
