વિધાન $-2$ : વેગમાન સંરક્ષણનો નિયમ તમામ પ્રકારના સંઘાત માટે સાચો છે.
Given if \(2\) particles move in same direction then in inelastic collisions they do not lose all their energy.
Let assume,
all energy is loss
\(\therefore\) velocity of both mass will \(0,\)
\(\underset{m_1}{\stackrel{u_1}{\longrightarrow} \stackrel{m_2}{\longrightarrow}} \stackrel{u_2}{\longrightarrow}\)
So, let apply Momentum conservation,
\(p_i=m_1 u+m_2 u_2\)
\(P_f=0 \quad\) [velocity of both mass is 0\(]\).
\(\therefore\) Here, Momentum is not conserved
\(\therefore\) statement\(-1\) is true.
Statement \(-2\) is universally true,
and statement\(-2\) is also explanation of statement \(-1.\)
Hence,
statement \(1\) is true, statement\(-2\) is true,
statement \(-2\) is the correct explanation of statement \(1\)
