What happens to the kinetic energy of a body when its velocity is doubled?
A
Triples
B
Doubles
C
Becomes four times
D
Remains the same
Correct Answer: Option C — Becomes four times
Explanation:
Since kinetic energy is proportional to the square of velocity, doubling the velocity of a body increases its kinetic energy by a factor of ...
Since kinetic energy is proportional to the square of velocity, doubling the velocity of a body increases its kinetic energy by a factor of four, assuming the mass remains unchanged throughout.
