1. What is Momentum?

Momentum is a fundamental concept in physics that describes the quantity of motion an object possesses. It is a vector quantity, meaning it has both magnitude and direction, and is conserved in isolated systems.

2. How Does the Calculator Work?

The calculator uses the momentum formula:

Where:

• \( p \) — Momentum (kg·m/s)
• \( m \) — Mass (kg)
• \( v \) — Velocity (m/s)

Explanation: Momentum is directly proportional to both mass and velocity. Doubling either mass or velocity will double the momentum.

3. Importance of Momentum Calculation

Details: Momentum calculations are crucial in understanding collisions, conservation laws, rocket propulsion, and various engineering applications. It helps predict the outcomes of interactions between objects.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers. The calculator will compute the momentum in kilogram-meters per second (kg·m/s).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between momentum and velocity?
A: Velocity describes how fast an object is moving and in what direction, while momentum describes the quantity of motion and depends on both mass and velocity.

Q2: Is momentum conserved in all situations?
A: Momentum is conserved in isolated systems where no external forces act. In real-world scenarios with friction or air resistance, momentum may not be perfectly conserved.

Q3: Can momentum be negative?
A: Yes, since momentum is a vector quantity, it can be negative when the direction is opposite to the chosen positive direction.

Q4: How does momentum relate to force?
A: Force is equal to the rate of change of momentum (Newton's second law: F = dp/dt).

Q5: What are practical applications of momentum?
A: Car safety design (crumple zones), sports (following through in baseball), rocket launches, and particle physics experiments all rely on momentum principles.
