Question
Potential energy cannot be
- Positive
- Negative
- Zero
- Infinity
Hint:
The Potential energy depends on the height at which the object is placed.
The correct answer is: Negative
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, as long as the object is at ground level, potential energy cannot be negative.
