| Apr 13, 2017 at 18:01 | comment | added | Shashaank | @KunalPawar A collision or crash is an event in which two or more bodies exert forces on each other for a relatively short time. Although the most common colloquial use of the word "collision" refers to incidents in which two or more objects collide, the scientific use of the word "collision" implies nothing about the magnitude of the force. | |
