What are The three stages of collision?

Answer 1

The three stages of collision are:

1st stage - vehicle crash,

2nd stage - human crash, and

3rd stage - internal crash.

Answer 2

Types of collisions1. Inelastic collision: conserved, but not KE. Example - rubber ball on a hard surface (ball deforms internal elastic PE ). 2. Perfectly inelastic collision: Two objects stick together v1f = v2f vf . conserved, but not KE. Conservation of gives,
m1v1i + m2v2i = (m1 + m2)vf. (6)

Example - two lumps of clay. 3. Elastic collision: and KE are conserved. Example - two billiard balls (no deformations). We have,
m1v1i + m2v2i = m1v1f + m2v2f, (7) m1v1i2 + m2v2i2 = m1v1f2 + m2v2f2. (8)

By combining these two equations we obtain a third (dependent) equation that tells us that the relative velocity before collision is the negative of the relative velocity after collision:

Answer 3

There are three stages of a collision. These include the vehicle collision, the human collision, as well as the internal collision.
