# What is the difference between elastic and inelastic collisions?

Today I will explain the difference between elastic and inelastic collisions in detail.

## Elastic Motion

• K.E is conserved.
• P.E is conserved.
• No energy is lost whatsoever.
• If a ball is bouncing with elastic motion, it would keep bouncing infinitely and height of re-bounce does not change as it loses no energy to sound or friction.

## Inelastic Motion

• K.E is not conserved.
• P.E is not conserved.
• Energy is lost.
• If a ball is bouncing non-elastically, it would bounce sometimes and then settle down on ground.

K.E is mostly lost in various cases as no matter what we do, the sytem cannot be 100% efficient and some energy is lost to sound, friction or momentum.

## Conclusion

I hope you have understood the difference between elastic and inelastic collisions. I would be very thankful if you’d help it spread by emailing it to your friends or sharing it on Facebook, Reddit, Pinterest, Twitter, or Instagram. Thank you!
