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 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 stored in an object when it is raised to a certain height against gravity.
Details: Calculating potential energy is fundamental in physics and engineering for understanding energy conservation, mechanical systems, and designing structures like dams and roller coasters.
Tips: Enter mass in kilograms, gravitational acceleration in m/s² (9.8 for Earth), and height in meters. All values must be positive numbers.
Q1: What is the standard value of g on Earth?
A: The standard gravitational acceleration on Earth is approximately 9.8 m/s², though it varies slightly depending on location and altitude.
Q2: Can potential energy be negative?
A: Yes, potential energy can be negative when the reference point is set above the object's position, particularly in gravitational systems with different reference frames.
Q3: How does potential energy convert to kinetic energy?
A: When an object falls, its potential energy decreases while its kinetic energy increases, following the principle of conservation of mechanical energy.
Q4: Does the formula work on other planets?
A: Yes, but you need to use the specific gravitational acceleration value for that planet (e.g., 1.62 m/s² for the Moon, 3.71 m/s² for Mars).
Q5: What are real-world applications of potential energy?
A: Hydroelectric power generation, pendulum clocks, roller coasters, and weightlifting are all examples that involve potential energy calculations.
