JEE Main Physics question

Physics Work, Energy and Power JEE Main

Statement 1: According to the law of conservation of mechanical energy, change in potential energy is equal and opposite to the change in kinetic energy. Statement 2: Mechanical energy is not a conserved quantity.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is FalseCorrect
(D)Assertion is False, Reason is True

Answer: (C)

Solution

For a conservative system, ΔK + ΔU = 0, i.e. ΔK = −ΔU, confirming Statement 1. Mechanical energy
