Potential Energy Formula:
| From: | To: |
Potential energy is the energy stored in an object due to its position relative to other objects. Gravitational potential energy specifically refers to the energy an object possesses because of its position in a gravitational field.
The calculator uses the potential energy formula:
Where:
Explanation: The formula calculates the energy an object has due to its position in a gravitational field, with Earth's standard gravity being approximately 9.81 m/s².
Details: Calculating potential energy is fundamental in physics and engineering for understanding energy conservation, designing mechanical systems, and analyzing motion in gravitational fields.
Tips: Enter mass in kilograms, gravitational acceleration in m/s² (9.81 for Earth), and height in meters. All values must be positive numbers.
Q1: What is the standard value for gravity on Earth?
A: The standard acceleration due to gravity on Earth is approximately 9.81 m/s², though it varies slightly depending on location and altitude.
Q2: Can this calculator be used for other planets?
A: Yes, simply adjust the gravity value to match the gravitational acceleration of the other celestial body (e.g., 1.62 m/s² for the Moon).
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 point.
Q4: How does potential energy relate to kinetic energy?
A: Potential energy can be converted to kinetic energy as an object falls, following the principle of conservation of mechanical energy.
Q5: Are there other types of potential energy?
A: Yes, other forms include elastic potential energy (in springs), chemical potential energy, and electrical potential energy.
