Potential Energy Formula:
| From: | To: |
Potential Energy is the energy stored in an object due to its position relative to other objects. It represents the potential an object has to do work as a result of its position in a gravitational field.
The calculator uses the gravitational potential energy formula:
Where:
Explanation: This formula calculates the energy an object possesses due to its position in a gravitational field. The higher the object or the greater its mass, the more potential energy it stores.
Details: Calculating potential energy is crucial in physics, engineering, and various applications including mechanical systems, energy storage, and understanding conservation of energy principles in physical systems.
Tips: Enter mass in kilograms, height in meters, and gravitational acceleration (default is Earth's gravity 9.81 m/s²). All values must be positive numbers.
Q1: What is the difference between potential and kinetic energy?
A: Potential energy is stored energy due to position, while kinetic energy is energy of motion. Potential energy can be converted to kinetic energy when an object falls.
Q2: Does the formula work for all gravitational fields?
A: Yes, but you need to use the appropriate gravitational acceleration value for the specific celestial body (e.g., 1.62 m/s² for the Moon, 3.71 m/s² for Mars).
Q3: What is the reference point for height measurement?
A: The reference point is typically the lowest possible position in the system being analyzed, often ground level or a defined zero potential energy point.
Q4: Can potential energy be negative?
A: In some coordinate systems, potential energy can be negative relative to a reference point, but in the standard gravitational formula, it's always positive when height is positive.
Q5: How does this relate to conservation of energy?
A: In a closed system, the total mechanical energy (potential + kinetic) remains constant, demonstrating the principle of energy conservation.
