Calculate The Momentum Of An Object In Java

 An object's momentum is its mass multiplied by its velocity. Write a program that expects an object's mass (in kilograms) and velocity ( in meters per second) as inputs and prints its momentum.

This program used Scanner method for getting user's input. Save this file as Momentum.java.

01	import java.util.Scanner;

02

03	public class Momentum {

04	public static void main(String [] args) {

05	Scanner in      = new Scanner(System.in);

06	double mass     = 0.0;

07	double velocity = 0.0;

08

09	System.out.print("Enter object's mass in kilograms: ");

10	mass = in.nextDouble();

11

12	System.out.print("Enter object's velocity in meter/second: ");

13	velocity = in.nextDouble();

14

15	System.out.println("The momentum is: " + (mass * velocity));
