Potential Energy Formula:
| From: | To: |
Potential energy is the energy stored in an object due to its position relative to other objects, stresses within itself, its electric charge, or other factors. Gravitational potential energy is specifically 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, which can be converted to kinetic energy when the object falls.
Details: Calculating potential energy is essential in physics and engineering for understanding energy conservation, designing mechanical systems, and analyzing the behavior of objects 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 of gravitational acceleration?
A: On Earth's surface, the standard value is approximately 9.81 m/s², though it varies slightly with location and altitude.
Q2: Can potential energy be negative?
A: In some reference systems, potential energy can be negative, but in the standard gravitational potential energy formula, it's typically positive when measured above the reference point.
Q3: How does potential energy relate to kinetic energy?
A: As an object falls, its potential energy decreases while its kinetic energy increases, following the principle of conservation of energy.
Q4: What are some real-world applications of potential energy calculations?
A: Applications include designing hydroelectric dams, calculating energy storage in elevated weights, and analyzing projectile motion.
Q5: Does the formula work for any planet?
A: Yes, but you need to use the appropriate gravitational acceleration value for that specific celestial body.
