Question

Assertion :- The kinetic energy, with any reference, must be positive.
Reason:- In the expression for kinetic energy, the velocity appears with power 2
and mass is a scalar quantity.
a)
b)
c)
d)​

Answer 1

Answer:

We know that the kinetic energy of a body is represented as K=12mv2. ... So we can say that kinetic energy is always positive. Therefore, both assertion and reason are CORRECT and the reason is the CORRECT explanation of the assertion. Hence option A is correct.

The kinetic energy, with any reference, must be positive. Reason: In the expression for kinetic energy, the velocity appears with power 2. (A) Both assertion and reason are CORRECT and the reason is the CORRECT explanation of the assertion.
