1. What is the Momentum Equation?

The momentum equation describes the relationship between an object's mass, velocity, and momentum. It is a fundamental concept in physics that quantifies the quantity of motion an object possesses.

2. How Does the Calculator Work?

The calculator uses the momentum equation:

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 is a conserved quantity in isolated systems, making it crucial for analyzing collisions, explosions, and other physical interactions. It's essential in mechanics, engineering, and various scientific applications.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be valid (mass > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are the SI units for momentum?
A: The SI unit for momentum is kilogram-meter per second (kg·m/s).

Q2: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.

Q3: How is momentum conserved in collisions?
A: In an isolated system, the total momentum before a collision equals the total momentum after the collision.

Q4: What's the difference between momentum and kinetic energy?
A: Momentum depends on mass and velocity (p = mv), while kinetic energy depends on mass and velocity squared (KE = ½mv²).

Q5: Can momentum be negative?
A: Yes, momentum can be negative when the velocity vector points in the negative direction of the chosen coordinate system.
