1. What is the Potential Energy Formula?

The potential energy formula calculates the energy stored in an object due to its position in a gravitational field. It is commonly used in physics to determine the energy an object possesses when elevated above a reference point.

2. How Does the Calculator Work?

The calculator uses the potential energy equation:

\[ E_p = m \times g \times h \]

Where:

\( E_p \) — Potential energy (Joules)
\( m \) — Mass of the object (kilograms)
\( g \) — Gravitational acceleration (m/s²)
\( h \) — Height above reference point (meters)

Explanation: The formula multiplies mass by gravitational acceleration and height to calculate the potential energy in joules.

3. Importance of Potential Energy Calculation

Details: Calculating potential energy is essential in various fields including engineering, physics, and energy management. It helps determine the energy storage capacity in elevated objects and is fundamental in understanding energy conservation principles.

4. Using the Calculator

Tips: Enter mass in kilograms, gravitational acceleration in m/s² (Earth's gravity is approximately 9.81 m/s²), and height in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard value for gravitational acceleration?
A: On Earth, the standard gravitational acceleration is approximately 9.81 m/s², though it varies slightly depending on location and altitude.

Q2: Can this formula be used on other planets?
A: Yes, but you need to use the specific gravitational acceleration value for that celestial body.

Q3: What are the units of potential energy?
A: Potential energy is measured in joules (J) in the International System of Units.

Q4: Does air resistance affect potential energy calculations?
A: No, potential energy calculation only considers mass, gravity, and height. Air resistance affects kinetic energy during motion.

Q5: How is potential energy related to kinetic energy?
A: When an object falls, potential energy converts to kinetic energy. The total mechanical energy (potential + kinetic) remains constant in a closed system without friction.
