Match the following
 

S.No.	Column-I	S.No.	Column-II
a)	Elastic collision	i)	e = 0
b)	Inelastic collision	ii)	0 < e < 1
c)	Explosion	iii)	e = 1
d)	Plastic collision	iv)	Final K.E. > initial K.E

	a	b	c	d
1)	i	ii	iii	iv
2)	iii	i	ii	iv
3)	iv	iii	ii	i
4)	iii	ii	iv	i

In explosion, chemical energy, stored in the explosive is released and appears as kinetic energy of the fragments .

In general, 0 $\le$ e $\le$ 1.
For perfectly inelastic collision or plastic collision, e = o.
For perfectly elastic collision, e = 1
For partially inelastic collision, 0<e<1
