Why principle of conservation of kinetic energy is not conserved during inelastic collision?

There is no law of conservation of kinetic energy. The law of conservation of energy says that energy cannot be created or destroyed, although it can be converted to different forms of energy. In inelastic collisions, kinetic energy is often transformed to heat energy, potential energy, and perhaps sound energy

How do you calculate velocity after perfectly collision?
To calculate the velocity after a perfectly elastic collision, you need to apply the principle of conservation of momentum and kinetic energy. First, find the initial momentum of the system before the collision by adding the momenta of the objects involved. Then, find the final momentum after the collision by equating it to the initial momentum. Next, solve for the final velocities of the objects by dividing the final momentum by their respective masses. Finally, make sure to check if the kinetic energy is conserved by comparing the initial and final kinetic energy values.
Is the Law of Conservation of Matter a basic principle in studying chemical reactions?
yes
Is The Law of Conservation of Matter is a basic principle in studying chemical reactions?
yes
Is the principle of conservation of momentum always valid?
Yes. As far as I am aware, no exceptions are known.
What is the term that means the knowledge that quantity is unrelated to the arrangement and physical appearance of objects?
Principle of conservation
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.
1 In a collision that is inelastic the total what after the collision is not the same as before the collision?
Hi, in line with Newton's laws of motion the momentum before and after a collision is always conserved (when no external force is applied to change the systems momentum). In elastic collisions we can apply the conservation of momentum and conservation of energy principles. In inelastic collisions we can only apply the conservation of momentum principle. Energy is not conserved in inelastic collisions because energy is lost through small deformations, noise, friction, etc. We can compute the coefficient of restitution that helps determine this degree of energy loss from impulse-momentum equations.
When a moving object with momentum collides with another moving object with momentum what formula do I use?
If the two bodies form a closed and isolated system (that is no other external forces act on the system apart from the forces that the bodies exert on each other and no mass is allowed to enter or leave the system), the principle of conservation of momentum SHOULD be used. Remember: As long as the condition in the brackets above hold, the principle of conservation of momentum holds. Next, depending on the nature of the collision, another conservation law can be used. If the collision is perfectly elastic, then kinetic energy is conserved. Note that although kinetic energy is not always conserved, TOTAL energy is ALWAYS conserved. You could still apply the principle of conservation of energy for an inelastic collision provided you knew the amount of energy converted to other forms of energy.
what is the role of Joule's experiment in establishing the principle of conservation of energy?
total energy IS CONSERVED and the principle of conservation of energy does hold
A car and a truck have a collision The truck has a mass 8 times the mass of the car if the truck is moving at 60kmhr and the car is stationary how fast do the two move after their inelastic collision?
I will assume that the collision is completely inelastic (that is, the truck and the car coalesce, moving off with the same velocity after the collision). This assumption is crucial as without it, the question cannot be solved if the inelastic collision is maintained.Let the mass of the car be m. The mass of the truck is 8m.From the principle of conservation of momentum;8m(60) = (8m + m)vwhere v is the final velocity.So, v = 8(60)/9v = 53.3 km/h
What is the momentum conservation's principle?
After a collision,The initial momentum of a system is equal to final momentum. m1V1=m2V2
What is the principle of conservation of thermal energy?
There is no such principle. Thermal energy can convert to other forms of energy, and vice-versa. The TOTAL energy (thermal + other kinds of energy) is conserved in a close system.

When two bodies having same momentum collide what will be the result?
There are two possible results. However, they cannot move in the same direction after the collision.Total initial momentum = p - p = 0where p represent the momentum of each object.From the principle of conservation of momentum;Total initial momentum = Total final momentumThus, Total final momentum = 0There are only two possibilities for this:1. Kinetic energy is conserved. (the collision is perfectly elastic)In this case, they would move away from each other with the same magnitude of initial momentum.2. Kinetic energy is not conserved. (the collision is inelastic)In this case, they would either remain at rest or they will move away from each other with a smaller magnitude of initial momentum each had.Note that if both bodies had moved in the same direction, there would be a net momentum in this direction and momentum would not have been conserved. (Momentum is ALWAYS conserved provided there is no external force acting on the system)
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.
What is conserved of electric charge?
: a principle in physics: the total electric charge of an isolated system remains constant irrespective of whatever internal changes may take place
How do you find the final velocity of two objects coupled?
The case you're describing is called an inelastic collision. Two objects collide, stick to each other and continue their motion as one body. Due to momentum conservation principle, sum of two bodies momenta before collision has to be equal to momentum of the one body after collision. pbefore = pfirst + psecond = m1v1 + m2v2 pafter = (m1 + m2)vcommon Since pbefore = pafter, (m1 + m2)vcommon = m1v1 + m2v2 We can get vcommon from that: vcommon = (m1v1 + m2v2) / (m1 + m2) [vi are velocities of bodies before collision and vcommon is a velocity after collision]
