Q746
For a freely falling body, the sum of kinetic energy and potential energy is always
A.
Zero
B.
Unity
C.
Same
AnswerD.
Variable
Answer: Option C
Solution
Answer: Option C
Solution:
The sum total of the potential energy and the kinetic energy of the object during its free fall remains the same, i.e., the total mechanical energy (potential energy + kinetic energy) remains constant. Thus, the law of conservation of energy is not violated.
