A billiard ball will stop short when it collides head-on with a ball at rest the ball cannot stop short however if the collision is not exactly head on why?

The momemtum trasnsferred is only partial, mvcos(angle). If angle is not zero, there is momentum not transfered and thus left to move the incident ball.

The collision between two helium atoms is perfectly elastic so that momentum is conserved?
Momentum is always conserved in any type of collision. Energy conservation, however, is dependant on elasticity. In a perfectly elastic collision all energy is conserved.
Need an explanation why kinetic energy is always conserved during elastic collision what is meant by conserved?
In this context "conserved" means the total kinetic energy of all the objects is the same after the collision as before the collision. Note, the TOTAL is the same but the individual kinetic energies of each object may be different before and after. When two or more objects are about to collide they have a certain total kinetic energy. It is common that during the collision some of the kinetic energy is transformed into heat. So after the collision the total kinetic energy is less then before the collision. This is a non-elastic collision. There are some collisions, however, in which none of the kinetic energy is changed to heat. These are called ELASTIC collisions. So the total kinetic energy doesn't change, or is "conserved". There is another possible non-elastic collision. If during the collision there is an explosion, then its possible for the objects to have a larger total kinetic energy after the collision as they aquire some of the explosive energy. Finally note, that in all collisions the TOTAL vector momentum is the same just before and just after the collision. So in a collision momentum is always conserved.
Which physical quantity remains constant in an elastic collision?
In a uniform circular motion,the magnitude of velocity remains constant,that is speed is constant,however due to change in direction in circular path constantly the motion is accelerated due to change in velocity.
Which of the conservation law does not apply to an inelastic collision?
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
Why in a collision momentum is not always conserved?
In principle momentum is always conserved. However what sometimes happens in a collision is that energy is released that is then no longer considered part of the system. For example if two cars collide energy could be dissipated via the air and ground (e.g. heat) and this can also carry away momentum. Often, these effects are not taken into account and in that way momentum conservation appears to be violated; but if one takes care and takes into account all collision products the total momentum after is equal to the total momentum prior. So in short, any violation can be traced back to a redefinition of the system.
How much do billiard supplies cost?
Billiard supplies can be quite expensive, like the cost of maintaining the table, however the cues and balls are less expensive and can be bought from most sporting retailers.
2 types of air masses that form a tornado?
Most often a warm, moist air mass collides with a cool air mass, a cold air mass, or both. However, such a collision alone will only form thunderstorms. Other factors are needed for those storms to produce tornadoes.
When did segregation in US begin?
The start of segregation collides with the end of the Civil War which was in 1865. However, blacks and whites were separated before that.
Is there a billiard game called STARS?
No. there is no recognized billiards game called STARS. However, there may be a local game somewhere referred to as STARS.
Is there a rule of distance of school from billiard halls?
In the US there is no minimum distance. However, a local municipality can require a minimum distance by local code or ordinance.

Will the sun burn out before the Andromeda galaxy collides with our Milky way galaxy?
By the current best estimates, no. The sun will likely enter its red giant stage in about 5 billion years. The collision with the Andromeda galaxy is expected to occur in 3 to 4 billion years.
Is billiards singular or plural?
It is singular to refer to the game. However, a shot may be called a billiard and in that case, billiards can refer to multiple shots and would be plural.
Where was first indoor billiards game played?
There is no record of the first indoor billiards game. However, it is known that in 1429 billiards was played indoors on a billiard table in France.
How much do supplies cost?

Why are billiard tables covered in felt?
The felt surface of a billiard table may be the result of the Gorina fabrics company.Technically, it is not felt, although this term is used to describe the fabric. Felt is not a woven cloth, while the billiard table fabric is a woven wool that is technicall y referred to as baize.This material is specifically designed and developed for pool table use by many different fabric manufacturers. Each type that is available is different in some way and is chosen for the way the balls act and react on the surface and for lifespan of the cloth.It is not known when the types of fabrics now in use were developed. However, one of the first manufacturers of billiard table cloth is Gorina - they began in 1835. Very likely, this company was responsible for the billiard table felt we use today, though they are not credited with its invention.Read more: Why_is_a_billiard_table_made_of_felt
Always Buy Billiard Supplies Relating to Items that Decrease?
When looking at billiard supplies, you may decide that you do not need an extra set of billiard balls. After all, you are probably not going to lose them if you are just playing in your basement. However, you need to make sure that you have extra supplies for items that you know are going to decrease over time. This could include cues, which are going to break at some point. The most notable example, though, is chalk. The chalk will naturally run out as it is used, so you always need to have more of it on hand.
