Energy transformations during rocket launch

Steps:

• Chemical energy in rocket fuel converts to thermal and kinetic energy via combustion.
• This kinetic energy propels the rocket upward, increasing its speed.
• As height increases, gravitational potential energy rises proportionally to height.
• All three energies change simultaneously as the rocket leaves the pad.

Why A is correct:

• Conservation of energy law states chemical energy transforms into kinetic (motion) and gravitational potential (height), all decreasing or increasing accordingly.

Why the others are wrong:

• B: Ignores gravitational potential energy gain from rising altitude.
• C: Excludes kinetic energy from propulsion and motion.
• D: Omits chemical energy as the initial source driving the launch.

Final answer: A
