1. What Is The Momentum Equation?

The momentum equation (p = m × v) calculates the quantity of motion of a moving object, where p represents momentum, m is mass, and v is velocity. It's a fundamental concept in physics that describes how difficult it is to stop a moving object.

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: 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 calculations are essential in physics for understanding collisions, conservation of momentum, rocket propulsion, and analyzing motion in various mechanical 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, the total momentum before a collision equals the total momentum after the collision (law of conservation of momentum).

Q4: What's the difference between momentum and kinetic energy?
A: Momentum depends on mass and velocity (p = m×v), while kinetic energy depends on mass and velocity squared (KE = ½mv²). Both are conserved in elastic collisions.

Q5: Can momentum be negative?
A: Yes, momentum can be negative when the velocity vector points in the negative direction of the chosen coordinate system.
