Gravitational Acceleration Calculator in Java

📌 Description

This is a simple Java console program that calculates the gravitational acceleration (g) at a given height above the Earth's surface. The user is prompted to enter a height (in meters), and the program outputs the corresponding gravitational acceleration based on Newton's Law of Universal Gravitation.

🧪 Formula Used

The formula used in the program is:

g = (G * M) / (R + h)²

Where:

• G = 6.674 × 10⁻¹¹ N·m²/kg² (gravitational constant)
• M = 5.972 × 10²⁴ kg (mass of the Earth)
• R = 6.371 × 10⁶ m (radius of the Earth)
• h = height above Earth's surface (input from user)
• g = gravitational acceleration at height h

🚀 How to Run

1. Make sure you have Java installed on your system.
2. Save the code in a file named Gravitacija.java.
3. Open a terminal and compile the program: javac Gravitacija.java
4. Run the compiled class: java Gravitacija
5. Enter the height when prompted (e.g., 0, 1000, 1000000).

📄 Example Output

Vnesete visina (v metrih)

1000000

Pospesek je enak: 7.337700 m/s^2

Visina je enaka: 1000000 m
