1. What is Momentum?

Momentum is a measurement involving the motion of an object in motion and is calculated by multiplying the mass of the object by its velocity. It is a vector quantity, meaning it has both magnitude and direction.

2. How Does the Calculator Work?

The calculator uses the momentum equation:

Where:

• \( p \) — Momentum (kg·m/s)
• \( m \) — Mass of the object (kg)
• \( v \) — Velocity of the object (m/s)

Explanation: The momentum of an object is directly proportional to both its mass and velocity. Doubling either the mass or velocity will double the momentum.

3. Importance of Momentum Calculation

Details: Momentum is a fundamental concept in physics that describes the quantity of motion an object has. It's crucial for understanding collisions, conservation laws, and motion in general.

4. Using the Calculator

Tips: Enter 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 for momentum is kilogram meters per second (kg·m/s).

Q2: How is momentum different from velocity?
A: Velocity only describes how fast something is moving and in what direction, while momentum incorporates both the object's mass and its velocity.

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

Q4: Can momentum be negative?
A: Yes, since velocity is a vector quantity, momentum can be negative if the object is moving in the negative direction of your coordinate system.

Q5: How does momentum relate to force?
A: Force is equal to the rate of change of momentum (Newton's second law: F = dp/dt).
