WBCS.LIVE practice question

If the velocity of a moving body is doubled, what happens to its kinetic energy?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. It becomes four times.
  2. It gets doubled.
  3. It becomes half.
  4. It remains the same.

Correct answer and explanation

Correct answer: It becomes four times.

Explanation: ✅ Correct Answer: A) It becomes four times. 📚 Explanation: The kinetic energy of an object is directly proportional to the square of its velocity (KE = 1/2 mv²). If the velocity of the moving body is mathematically doubled, the square of the velocity factor becomes four times larger (2² = 4). Therefore, the overall kinetic energy of the object increases by a factor of four.
