Simulated nuclear collisions

Extracts from this document...

Introduction

Ponmuhil Ravichandran

Physics lab

Simulated nuclear collisions

Aim:

  1. To simulate the relationship between the kinetic energy of a nuclear particle and it’s stopping distance in a detection device.
  2. To show that energy momentum are conserved in nuclear collisions.

Theory: Given in the lab sheet

Equipment: Given in the lab sheet

Procedure: Given in the lab sheet

Data collection:

Part1: Energy measurements

The stopping distances for each of the different trials, released at heights are recorded below:

Observation: When the incident coin hit the target coin, the incident coin almost stopped immediately upon impact, while the target coin moved a distance, as recorded above.

Part3: Two-dimensional collisions

The distances traveled by the incident and the target nickels for each of the different trials, released at different heights are recorded below:

Conclusion

If the kinetic energy is directly proportional to the height of the falling object, then this also implies that the higher the kinetic energy, the higher will be the stopping distances. Therefore, a relationship between kinetic energy and stopping distances has been obtained through the experiment.

Overall, the experiment was carried out completely without any major errors. In future, the experiment could be improved by taking more care in being accurate, when releasing the coins.
