1. What is Momentum?

Definition: Momentum is a measurement involving the motion of an object in motion and is the product of the mass and velocity of an object.

Purpose: It's a fundamental concept in physics that describes the quantity of motion an object has and helps analyze collisions and motion.

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 mass of the object is multiplied by its velocity to determine its momentum.

3. Importance of Momentum Calculation

Details: Momentum is conserved in isolated systems and is crucial for understanding collisions, motion, and force applications in physics.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: How does momentum differ from velocity?
A: Velocity only considers speed and direction, while momentum also incorporates the object's mass.

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

Q4: Can momentum be negative?
A: Yes, momentum can be negative when the velocity is negative (indicating opposite direction).

Q5: How is momentum related to force?
A: Force equals the rate of change of momentum (Newton's Second Law: F = Δp/Δt).
