1. What is the Momentum Equation?

The momentum equation (p = m × v) describes the quantity of motion an object has, where p is momentum, m is mass, and v is velocity. It is a fundamental concept in classical mechanics.

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 interactions in physics. It's essential for understanding motion and predicting outcomes of physical interactions.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are the units of momentum?
A: Momentum is measured in kilogram-meters per second (kg·m/s) in the SI system.

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 different from velocity?
A: Velocity measures speed with direction, while momentum incorporates both the object's mass and its velocity.

Q4: What is the conservation of momentum?
A: In a closed system with no external forces, the total momentum before an interaction equals the total momentum after the interaction.

Q5: Can momentum be negative?
A: Yes, since momentum is a vector, it can be negative when the direction of motion is opposite to the chosen positive direction.
