1. What is the Momentum Formula?

The momentum formula calculates the quantity of motion of a moving body. It is defined as the product of an object's mass and velocity, represented by the equation p = m × v, where p is momentum, m is mass, and v is velocity.

2. How Does the Calculator Work?

The calculator uses the momentum formula:

Where:

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

Explanation: The formula demonstrates that momentum is directly proportional to both mass and velocity of an object.

3. Importance of Momentum Calculation

Details: Momentum is a fundamental concept in physics, particularly in mechanics. It's crucial for understanding collisions, conservation laws, and analyzing motion in various physical systems.

4. Using the Calculator

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

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 a closed system with no external forces, 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, since momentum is a vector quantity, it can be negative when the direction of motion is opposite to the chosen positive direction.
