Question

The kinetic energy of a body depends upon

• A. mass of the body
• B. velocity of the body
• C. height of the body
• D. both (a) and (b)

Answer 1

The correct option is D

both (a) and (b)

Correct Answer- Option (D)

Explanation of correct answer-

1. In physics, the kinetic energy of an object is the energy that it possesses due to its motion.
2. Mathematically, the kinetic energy of an object of mass m traveling at a speed v is given by: $\frac{1}{2}m{v}^2$
3. Hence kinetic energy depends upon the mass and velocity of the object, therefore option D is correct.

Explanation of incorrect answer-

Option C:

1. Kinetic energy does not depend upon the height of the object. Hence, option C is incorrect.

Hence, correct option is D: both (a) and (b)
