Q: If a boy leaves a gas-filled balloon that goes upward direction, its potential energy will be?
  • A. Decrease
  • B. Remains constant
  • C. It is infinite
  • D. Increase
Correct Answer: Option D - The potential energy in an object increases with increasing height. When a boy leaves a balloon filled with gas that goes upward direction the value of increases, thereby increasing the potential energy. Potential energy = mass × gravitational acceleration × height Potential energy ∝ h. Therefore, it is clear from the above equation that the potential energy will increases as the height increases and the potential energy will decrease as the height decreases.
