1. What is Momentum?

Momentum is a measurement involving the motion of an object in motion and the mass of the object. It is a vector quantity, possessing 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.

3. Importance of Momentum Calculation

Details: Momentum is fundamental in understanding collisions, explosions, and other interactions between objects. It's conserved in closed systems, making it crucial in physics problem-solving.

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: The standard SI unit is kilogram meters 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 different from velocity?
A: Velocity measures motion alone, while momentum incorporates both mass and motion.

Q4: What is the law of conservation of momentum?
A: In a closed system with no external forces, the total momentum remains constant.

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