Formula Used in “Potential Energy Calculator”
The potential energy (PE) of an object is calculated using the standard formula:
( PE = m cdot g cdot h )
Step-by-Step Breakdown of the Formula
In the formula above, each variable represents a specific quantity essential for calculating the potential energy of an object. Below is a detailed explanation of each variable:
- m – Mass of the object (in kilograms, kg): This represents the amount of matter present in the object.
- g – Acceleration due to gravity (in meters per second squared, m/s²): This value is approximately 9.81 m/s² on the surface of the Earth.
- h – Height of the object above the reference point (in meters, m): This indicates how high the object is positioned relative to a chosen base level.
Example Calculation
To illustrate how to use the potential energy formula, consider the following real-world example:
A rock with a mass of 5 kg is placed on a cliff that is 10 meters high. We will determine the potential energy of the rock at that height.
| Parameter | Value | Units |
|---|---|---|
| Mass (m) | 5 | kg |
| Acceleration due to gravity (g) | 9.81 | m/s² |
| Height (h) | 10 | m |
Calculating Potential Energy
Using the values from the table, we can plug them into the potential energy formula:
( PE = 5 , kg cdot 9.81 , frac{m}{s²} cdot 10 , m )
Simplifying the calculation:
( PE = 5 cdot 9.81 cdot 10 = 490.5 , J )
The potential energy of the 5 kg rock at a height of 10 meters is approximately 490.5 Joules (J).
