Calculate with code

These short examples use the same inputs and core calculation as this tool. Adapt validation and formatting to your application.

JavaScript
const massKg = 2, velocityMps = 3;
console.log(0.5 * massKg * velocityMps ** 2); // 9 J
TypeScript
const massKg = 2, velocityMps = 3;
const energy: number = 0.5 * massKg * velocityMps ** 2;
console.log(energy); // 9 J
Python
print(0.5 * 2 * 3**2)  # 9 J
Java
System.out.println(0.5 * 2 * Math.pow(3, 2)); // 9 J
C#
Console.WriteLine(0.5 * 2 * Math.Pow(3, 2)); // 9 J
