What happens to energy in a complete inelastic collision?

In summary, the conversation discusses the difference in results between the conservation of linear momentum and conservation of kinetic energy in a complete inelastic collision where one particle is at rest and the other collides with it, causing both to move together. It is mentioned that kinetic energy is only conserved in elastic collisions and the remaining energy can be converted into heat, internal energy, or sound depending on the type of collision. The conversation ends with the understanding that there is a specific amount of energy that is dissipated and this can vary depending on the circumstances.

Could be a stupid question. But in case of complete inelastic collision, when one particle is at rest and other one collides with it and both move together, I made calculations(pretty simple ones), the conservation of linear momentum and conservation of kinetic energy give different results.
Can anyone explain it?

They should, kinetic energy is only conserved in elastic collisions.

So, what happens to rest of the energy? Heat? Any law of thermodynamic?

Depends on the collision. Heat, internal energy, sound, etc.

I mean there's a precise amount of energy getting drained. It has to impact somewhere, like if in space, sound won't be a concern. If you can tell it more specifically. But thanks anyway, I got it. A burden out of my head.
 

1. What is a complete inelastic collision?

A complete inelastic collision is a type of collision where two objects collide and stick together after the collision. In this type of collision, kinetic energy is not conserved and some of the initial energy is converted into other forms of energy, such as heat or sound.

2. How is a complete inelastic collision different from an elastic collision?

In an elastic collision, both momentum and kinetic energy are conserved. The objects bounce off each other after the collision and there is no loss of energy. In a complete inelastic collision, only momentum is conserved and there is a loss of energy due to the objects sticking together.

3. What factors affect the outcome of a complete inelastic collision?

The mass and velocity of the objects involved in the collision are the main factors that affect the outcome of a complete inelastic collision. Objects with larger mass and higher velocity will have a greater impact and result in a more significant loss of kinetic energy.

4. What are some real-life examples of complete inelastic collisions?

Some examples of complete inelastic collisions in everyday life include a car accident where two cars collide and stick together, a ball hitting a wall and not bouncing back, and a person catching a ball and bringing it to a stop.

5. How is the concept of a complete inelastic collision used in scientific research?

In scientific research, the concept of a complete inelastic collision is used to understand the behavior of particles at the microscopic level. It is also used in fields such as mechanical engineering and materials science to study the impact of collisions on different materials and structures.
