Question

Analyze the given statements and choose the correct option.
Statement I : The kinetic energy, with any reference, must be positive.
Statement II : The kinetic energy and the square of velocity are related

• A. Both statement I and statement II are correct and statement II is the correct explanation of statement I
• B. Both statement I and statement II are correct, but statement II is not the correct explanation of statement I
• C. Statement I is correct, but statement II is incorrect
• D. Statement I is incorrect, but statement II is correct

Answer 1

The correct option is A Both statement I and statement II are correct and statement II is the correct explanation of statement I

Statement 1 is correct since kinetic energy is associated with motion it is always positive.

Statement 2 is also correct since kinetic energy is directly proportional to the square of the velocity and thus are related to each other.

Also statement 2 is the correct explanation of statement 1, since as mentioned kinetic energy is directly proportional to the square of the velocity, and square of any term is always positive, which is mentioned in the statement 1.
