The Potential Energy to Kinetic Energy Calculator is an invaluable tool that simplifies the process of converting stored energy (potential energy) into energy of motion (kinetic energy). This conversion is essential in fields like mechanical engineering, physics, and any application involving moving objects.
Formula of Potential Energy to Kinetic Energy Calculator
The formula for converting potential energy (PE) to kinetic energy (KE) involves the principle of energy conservation, where the total energy in a closed system remains constant. The formulas used are:
Potential Energy (PE): PE = m * g * h
- m = mass of the object (in kilograms)
- g = acceleration due to gravity (9.8 m/s² on Earth)
- h = height above the reference point (in meters)
Kinetic Energy (KE): KE = 0.5 * m * v²
- v = velocity of the object (in meters per second)
Conversion Process
At the initial height, the object possesses maximum potential energy. As it falls, this energy is converted into kinetic energy. When all the potential energy is converted at a lower height, the energies equate as follows:
m * g * h = 0.5 * m * v²
Simplifying, we remove the mass, leading to:
g * h = 0.5 * v²
To find the velocity at which all potential energy is kinetic: v = sqrt(2 * g * h)
Table for General Terms
Here is a simple table detailing commonly used terms in energy calculations:
| Term | Definition |
|---|---|
| Mass (m) | The mass of the object in kilograms. |
| Gravity (g) | The acceleration due to gravity (9.8 m/s²). |
| Height (h) | The height above the reference point in meters. |
| Velocity (v) | The velocity of the object in meters per second. |
Example of Potential Energy to Kinetic Energy Calculator
Consider a 10 kg object at a height of 5 meters. Using the calculator:
PE = 10 * 9.8 * 5 = 490 joules
As it falls completely, KE at the ground would be 490 joules, indicating all potential energy has been converted to kinetic energy.
