1. What is the Momentum Equation?

The momentum equation (p = m × v) calculates the momentum of an object, where momentum is the product of an object's mass and its velocity. Momentum is a vector quantity that describes the quantity of motion an object possesses.

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: The equation shows that 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 fundamental concept in physics, particularly in mechanics. It's conserved in closed systems and is crucial for understanding collisions, explosions, and other interactions between objects.

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 is the unit of momentum?
A: The SI unit of momentum is kilogram-meter per second (kg·m/s).

Q2: Is momentum a scalar or vector quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.

Q3: What is the conservation of momentum?
A: In a closed system with no external forces, the total momentum before a collision equals the total momentum after the collision.

Q4: How does momentum relate to force?
A: Force is equal to the rate of change of momentum (F = Δp/Δt), as described by Newton's second law.

Q5: What is the difference between momentum and kinetic energy?
A: Momentum is mass times velocity (p = mv), while kinetic energy is half mass times velocity squared (KE = ½mv²). Both are conserved in elastic collisions.
