1. What is Momentum?

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

Purpose: It helps in understanding and calculating the motion of objects in physics and engineering applications.

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 crucial in understanding collisions, motion, and force in physics. It's conserved in closed systems and helps predict motion outcomes.

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 unit is kilogram meters per second (kg m/s).

Q2: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum includes both the object's mass and its velocity.

Q3: What happens to momentum in a collision?
A: In a closed system, the total momentum before and after a collision remains constant (conservation of momentum).

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

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