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?
What else can I help you with?
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.
Is ideal gas law elastic?
Yes, the ideal gas law describes the behavior of ideal gases, which are considered to be elastic. An elastic collision is one in which kinetic energy is conserved, and ideal gases are assumed to have elastic collisions between gas particles.
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.
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.
Is momentum conserved during an elastic collision?
Yes, momentum is conserved during an elastic collision.
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
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 momentum conserved in an elastic collision?
Yes, momentum is conserved in an elastic collision, meaning the total momentum of the system before the collision is equal to the total momentum after the collision.
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.
Is momentum conserved in elastic collisions?
Yes, momentum is conserved in elastic collisions. This means that the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.
Is kinetic energy conserved in an elastic collision?
Yes, kinetic energy is conserved in an elastic collision, meaning the total kinetic energy before the collision is equal to the total kinetic energy after the collision.
What is the difference between an inelastic collision and an elastic collision?
In an inelastic collision, kinetic energy is not conserved and some energy is lost as heat or sound. In an elastic collision, kinetic energy is conserved and no energy is lost.
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.
What is the relationship of velocity before and after impact?
The relationship between velocity before and after impact depends on the conservation of momentum and energy. In an elastic collision, the total momentum and total kinetic energy is conserved, so the velocity after impact can be calculated using these conservation principles. In an inelastic collision, some kinetic energy is lost during impact, so the velocity after impact will be less than the velocity before impact.
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.
How can one determine if a collision is elastic?
An elastic collision can be determined by observing if the total kinetic energy of the system is conserved before and after the collision. If the kinetic energy remains the same, the collision is elastic.
