1. What is Momentum (p = m × v)?

Definition: Momentum is the product of an object's mass and its velocity. It's a vector quantity with both magnitude and direction.

Note: While often confused, force (F = ma) is different from momentum (p = mv). Force changes momentum over time.

2. How Does the Momentum Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The greater the mass or velocity of an object, the greater its momentum. Momentum is conserved in closed systems.

3. Importance of Momentum in Physics

Details: Momentum is fundamental in analyzing collisions, understanding motion, and solving problems in mechanics. It's conserved in all physical processes.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between momentum and force?
A: Force (F = ma) causes changes in momentum over time (F = Δp/Δt). Momentum (p = mv) describes the quantity of motion an object has.

Q2: What are the units of momentum?
A: In SI units, momentum is measured in kilogram-meters per second (kg m/s).

Q3: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity - it has both magnitude and direction (same as velocity).

Q4: What is the principle of conservation of momentum?
A: In a closed system with no external forces, the total momentum remains constant before and after interactions.

Q5: How is momentum different from kinetic energy?
A: Kinetic energy (½mv²) is a scalar that depends on speed squared, while momentum (mv) is a vector that depends directly on velocity.
