Nah, brah. Momentum and kinetic energy are conserved, but velocity is not. Correct me if I am wrong but from how I interpret this, any collision cause the colliding bodies to change their direction. Thus velocity, which is a vector quantitiy containing direction, is by definition changed in an elastic collision. I guess speed, which is the magnitude of the velocity, can be considered as being conserved?

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.
Is momentum conserved in a perfectly inelastic collision?
In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
During the interval of collision is the momentum conserved?
well i know momentum remains same before and after collision... But what about the period during which collision takes place?
In what way does the big bang theory conform with the law of conservation of matter?
It doesn't. In General Relativity, energy (and therefore mass) is NOT conserved - and the Universe on a large scale is described, to a great extent, by General Relativity. The reason energy is not conserved is simply that the conditions for Nöther's Theorem are not fulfilled, due to the expansion of the Universe.Note that under ordinary, everyday circumstances, the conditions for Nöther's Theorem ARE fulfilled, and energy (and therefore mass) IS conserved.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
Is mechanical energy always conserved?
IF you use d'alemberts pinciple and it is aparantly, according to physics conserved in collisions, be they either elastic or non-elastic collisions

Distinguish beween and elastic and inelastic collision for wich type of collision is momentum conserved?
Momentum is conserved in both elastic and inelastic collisions. Mechanical energy is conserved only in elastic collisions. In inelastic collisions, part of the energy is "lost" - usually most of it would be converted to heat, eventually.
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.
How is momentum conversed?
it is only conserved in a percectly elastic collision.
What is the equation for an elastic collision?
Well technically you can use the same equation for elastic collisons to find the velocity. (first mass*its velocity)+(secind mass*its velocity)=(first mass*new Velocity)+(second mass*new velocity) OR... if its inelastic the seccond half of the equation can look like: (first mass+second mass)*Final Velocity and the formula for kinetic energy is: .5mv^2
What is similarity potential energy and elastic?
elastic is when the objects in the collision bounce off one another and ENERGY IS CONSERVED.
What is elastic and inelastic collision?
In an elastic collision, no kinetic energy is lost, and the relative speed of separation of the objects after the collision is the same as the relative speed before the collision. In an inelastic collision, part of the elastic energy is lost, and the relative speed after the collision is less.
In a collision what is conserved?
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
What conditions must be satisfied for momentum to be conserved in a system?
For momentum to be conserved in a system it must
Give two examples showing the conservation of momentum give one example where momentum is not conserved?
Momentum like mass will always be conserved in any process. Momentum is the product of mass and velocity of the object. It is symbolically denoted as p=m*v where p = momentum, m = mass and v = velocity
