What does elastic collision mean?
In an elastic collision, both kinetic energy and momentum are conserved. This means that the total kinetic energy before the collision is equal to the total kinetic energy after the collision, and the total momentum before the collision is equal to the total momentum after the collision.
What collision produces more energy?
That depends what you mean by "produce". You may be aware that you can't create energy where there was none before.In a perfectly elastic collision, no kinetic energy is lost.In an inelastic collision (the objects stick together after the collision), much of the kinetic energy is converted into other forms of energy, mainly heat.
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.
Relation between relaxation time and mean collision time?
The relaxation time is related to the mean collision time through the expression: relaxation time = mean collision time / (1 - f), where f is the fraction of collisions that result in thermalization. The mean collision time represents the average time between particle collisions, while the relaxation time is the time it takes for a system to reach thermal equilibrium after a perturbation.
What is the total momentous before and after collision?
I assume you mean the total MOMENTUM. The momentum depends on the situation. The only thing you can be sure of is that the total momentum after the collision will be the same as the total momentum before the collision. You can often use this to solve problems about collisions.
Why the value of coefficient of restitution of a perfectly plastic impact is 0?
Physicists distinguish between elastic and inelastic (and partially elastic) collisions. If you mean "elastic", the coefficient of restitution is 1. If you mean "inelastic", the coefficient of restitution is 0.Why? Because that's how "elastic" and "inelastic" collisions are DEFINED. If all the kinetic energy is maintained, the coefficient (relative speed after collision, divided by relative speed before the collision) is 1 - i.e., no movement is lost. If it is zero, all the movement energy (relative speed) is lost.
What does elastic collision mean?
In an elastic collision, both kinetic energy and momentum are conserved. This means that the total kinetic energy before the collision is equal to the total kinetic energy after the collision, and the total momentum before the collision is equal to the total momentum 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.
What does it mean that the collisions of gas particles are perfectly elastic?
In a perfectly elastic collision of gas particles, no kinetic energy is lost during the collision. This means that the total kinetic energy of the particles before the collision is equal to the total kinetic energy after the collision. As a result, the momentum and speed of the particles are conserved.
What happens when another object collides with another object?
Newton's Third Law is closely related to Conservation of Momentum. When objects collide, whether the collision is elastic or not, momentum is conserved. (An elastic collision is one in which mechanical energy is conserved. In an elastic collision, after the collision, the objects go away at the same relative speed at which they approached before the collision.)
Is water inelastic or elastic?
If by 'elastic', you mean stretchy, then no. Water, frozen or otherwise cannot stretch. When it's Ice it's solid, and is more likely to break if you try. As a liquid it cannot stretch, merely flow.
What collision produces more energy?

You may be aware that you can't create energy where there was none before.In a perfectly elastic collision, no kinetic energy is lost.In an inelastic collision (the objects stick together after the collision), much of the kinetic energy is converted into other forms of energy, mainly heat.
What does it mean the demand for a product is inelastic?
When the demand for a product is inelastic, the product has no close substitutes and can't be easily replaced. Therefore, when the price of the product raises, people buy roughly the same amount of the product because they need it too much. This is in comparison to an elastic demand, where people will buy less of a product when it becomes more expensive.

What good has inelastic supply and elastic demand a specific example of a good please?
Would someone answer my question please I need it due Monday :S Inelastic supply ensures a predictable level of supply and also a static cost price. Elastic demand would mean that you need to careful in planning your supply pipeline. if you order too much you may end up selling at or below cost or at lower than budgeted margins. Generally in a globalised open market these 2 conditions cannot exist for long. They are counter intuitive
What does elasticity of demand mean?
"Elasticity of demand" is the economic term for how much of something people want. If demand is inelastic, people will buy the same amount at any price (think insulin--a diabetic needs it and so will buy it at any price.). If demand is elastic, the price greatly affects how much people will buy (concert tickets for a B-rate band: the higher the price, the less people will come). This is very generalized: the topic is very complex and confusing when explained in economic terms. Recently the demand for gas, which used to be inelastic, has become elastic. The price has raised too high for people to keep buying what they usually did, and so travel plans have been curtailed due to this and less gas has been puchased. Even more recently, gas prices have lowered again, but demand cannot yet be said to be inelastic again. Altogether, inelastic demand does not affect supply, while elastic demand does.
What does elastic mean when referring to atoms?
When referring to atoms, elastic means the ability of an atom to return to its original shape or configuration after being subjected to stress or deformation. This property is related to the strength of the atomic bonds within the material.
