Question
Potential energy is negative, then the height is
- Positive
- Negative
- Zero
- None of the above
Hint:
Potential energy cannot be negative.
The correct answer is: None of the above
As we know,
Potential energy= mass x gravitational acceleration x height
The reference of the height is the ground level. So, when the object is on the ground, the potential energy of that object is zero. Thus, the potential energy increases and decreases with height. The height cannot be negative.
Thus, the answer is none of the above.
