During the interval of collision is the momentum conserved?
Wilekh2002
well i know momentum remains same before and after collision... But what about the period during which collision takes place?

Comparison between elastic and inelastic collision?
In an elastic collision, all initial kinetic energy is fully restored as final kinetic energy. where nothing is converted into noise, heat or any other form of energy. In an inelastic collision, kinetic energy is "lost" to thermal or sound energy.
How are momentum and centrifugal force related?
-- Momentum and centrifugal force are similar in the sense that both of them often arise during a discussion of mechanics, kinematics, elementary newtonian physics, etc. -- Momentum and centrifugal force are different in the sense that momentum exists, can be measured, has magnitude and direction, and is conserved, whereas centrifugal force is entirely fictitious and non-existent.
Is neutron number conserved in radioactive decay?
The number of neutrons is not conserved during decay.
A bullet of mass 10 grams moving with a velocity of 400 m s gets embedded in a freely suspended wooden block of mass 900 grams what is the velocity acquired by the block?
The answer is: The momentum (mv) after the collision is the same asthe momentum before it. The rest is just arithmetic.Before the collision, the momentum of the bullet is mv=(0.01)x(400) = 4 kg-m/sec.After the collision, the combined mass of the wood block plus the bullet is 910 gm.Its momentum mv=(0.910)x(v) = 4 kgm-m/sec.v = 4/0.910 = 4.396 m/sec .I've ignored the momentum lost during the embedding due to crunching and splintering,both because I don't know anything about the properties of the wood, and also becauseI wouldn't know what to do with them.
Why does RR interval of ECG vary during normal respiration?
The RR interval of ECG vary during normal respiration because of the sinus arrhythmia.
Does momentum conserved during collisions?
Energy, if collision is rigid, total momentum is a constant also.
What is conserved during collisions?
Linear momentum.
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.
What is transferred during a collision?

Conservation of linear momentum exp?
Linear momentum is mass times velocity. For a single point object, momentum is conserved, because the object will continue to move at a constant velocity. Nor will its mass change either. For a group of objects, too: When momentum is transferred, for example during a collision, any momentum lost by one object is gained by another. The total momentum remains constant.
How does conservation of momentum apply to collisions?
Momentum is always conserved. But if you want to verify, calculate the vector sum p = mv of both objects before the collision, and then calculate the vector sum p = mv of both objects after the collision. Your two vectors should be exactly equal.
What is conserved during necleus disintegration?
Several things are conserved, including:* Total mass * Total energy * Total charge * Total momentum * Rotational momentum * Baryon number is conserved in all known reactions, though there are reasons to believe that this is not a strict conservation law * Color charge
How does mass of an object affect the force it applies during a collision?
The affect of force on the object during collision is described by a quantity called momentum. It is defined as p = mv where = p is momentum, m = mass of the object and v is velocity.
When is momentum conserved?
its not possible.. momentum is always conservedYou could say that momentum, in its classical definition, is not conserved at relativistic velocities. Momentum is conserved at relativistic speeds if momentum is redefined as; p = γmov where mo is the "rest (invariant) mass" and γ is the Lorentz factor, which is equal to γ = 1/√(1-ʋ2/c2) and ʋ is the relative velocity. Some argue that the relativistic mass, m' = γmo, is unnecessary, in which case the proper velocity,defined as the rate of change of object position in the observer frame with respect to time elapsed on the object clocks (its proper time) can be used.Proper velocity is equal to v = γʋ, so p = mov. mo here is the invariant mass, where before it represented the "rest mass."The problem with Newton's p = mv, is that with this definition, the total momentum does not remain constant in all isolated systems, specifically, when dealing with relativistic velocities. Mass and or velocity is dependent on the relative velocity of the observer with respect to the isolated system.It is important to add that with this new definition momentum is conserved. With that said, my point is not to argue that momentum is not always conserved but to simply offer an explanation for the relatively (no pun intended) common statement "momentum is not conserved in ALL isolated systems" which could be where the original question stems from.
Why is more impulse delivered during a collision when bouncing occurs than during one when it doesn't?
because when it is bouncing, has more momentum than when it doesn't
