Q: If the velocity of an object moving at a certain height is increase 4 times, then what will be the change in the potential energy of the object?
  • A. Potential energy will be constant
  • B. Potential energy will be half of its original value
  • C. Potential energy will be doubled
  • D. Potential energy will be 4 times of its original value
Correct Answer: Option A - The energy that exists in each object due to its position or shape is called potential energy. According to the question, increasing the velocity of an object moving at a certain height four times will change its kinetic energy and not the potential energy. Therefore, potential energy of that object will remain constant.
