1. What is Momentum?

Momentum is a measurement involving the motion of an object in motion and is calculated by multiplying the mass of the object by its velocity. It is a vector quantity, meaning it has both magnitude and direction.

2. How Does the Calculator Work?

The calculator uses the momentum equation:

Where:

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

Explanation: The momentum of an object is directly proportional to both its mass and velocity. Doubling either the mass or velocity will double the momentum.

3. Importance of Momentum Calculation

Details: Momentum is a fundamental concept in physics, particularly in the study of collisions and conservation laws. It's crucial for understanding motion, designing safety features in vehicles, and analyzing sports mechanics.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum incorporates both the object's mass and its velocity, representing the "quantity of motion."

Q3: What is the law of 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.

Q4: Can momentum be negative?
A: Yes, since momentum is a vector quantity, a negative value indicates direction opposite to the chosen positive reference direction.

Q5: How does momentum relate to force?
A: Force equals the rate of change of momentum (Newton's second law: F = Δp/Δt).
