What is the Explanation for Inelastic Collisions in Physics?

Click For Summary
SUMMARY

Inelastic collisions occur when two bodies collide and stick together, resulting in a loss of kinetic energy. The key concept is that the total momentum of the system is conserved, but kinetic energy is not. Analyzing the collision from the center of mass frame reveals that the kinetic energy before the collision is greater than after, confirming the inelastic nature of the event. This understanding is crucial for A-Level physics students tackling collision problems.

PREREQUISITES
  • Understanding of momentum conservation principles
  • Familiarity with kinetic energy calculations
  • Knowledge of center of mass concepts
  • Basic physics concepts related to collisions
NEXT STEPS
  • Study the principles of momentum conservation in collisions
  • Learn how to calculate kinetic energy before and after collisions
  • Explore the concept of center of mass in detail
  • Investigate examples of inelastic collisions in real-world scenarios
USEFUL FOR

A-Level physics students, educators teaching collision dynamics, and anyone interested in understanding the principles of inelastic collisions in physics.

Hi everyone,

I am a student of A'Levels and I am having a problem with a Question regarding inelastic collision the question is as follows:

Whenever two bodies collide and they stick together the collision is essentially inelastic. Explain?

Can anybody help me out with this this is a challenge from my physics teacher...I tried it but no good so please help me out...:) following is my answer which my teacher said is not correct...

Analyze the collision in the frame of reference of the centre of mass of the two colliding objects. What is the kinetic energy before the collision? What is it after?
