Question

In a collision between two particles , total number of correct statements out of the following is : i) kinetic energy is conserved during elastic collision ii) momentum is conserved during collision iii) momentum is conserved only before and after collision iv) conservation of momentum during collision depends on the type of collision v) kinetic energy is not conserved during collision PLEASE ANSWER CORRECTLY IF YOU SPAM I WILL REPORT

Answer 1

Answer:

1. An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. ... Some collisions between atoms in gases are examples of perfectly elastic collisions

2. In a collision, the momentum change of object 1 is equal to and opposite of the momentum change of object 2. That is, the momentum lost by object 1 is equal to the momentum gained by object 2. ... The total momentum of the system (the collection of two objects) is conserved.

3. For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

4. The total momentum of a system is conserved only when the system is closed. An elastic collision is one that conserves kinetic energy. An inelastic collision does not conserve kinetic energy. Momentum is conserved regardless of whether or not kinetic energy is conserved.

5. An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.
