1. What is Momentum?

Definition: Momentum is a measurement involving the motion of an object in motion and its resistance to stopping.

Purpose: It helps physicists and engineers understand and predict the motion of objects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( p \) — Momentum (kg m/s)
• \( v \) — Velocity (meters per second)
• \( m \) — Mass (kilograms)

Explanation: The velocity of an object multiplied by its mass equals its momentum.

3. Importance of Momentum Calculation

Details: Momentum is crucial in understanding collisions, vehicle safety, sports physics, and many engineering applications.

4. Using the Calculator

Tips: Enter the velocity in meters per second and mass in kilograms. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of momentum?
A: The standard unit is kilogram meters per second (kg m/s).

Q2: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum incorporates both speed and mass.

Q3: What happens to momentum in a closed system?
A: In a closed system with no external forces, total momentum is conserved.

Q4: Can momentum be negative?
A: Yes, when direction is considered, opposite directions have opposite signs.

Q5: How does momentum relate to force?
A: Force equals the rate of change of momentum over time (Newton's Second Law).
