1. What is Momentum?

Momentum is a fundamental concept in physics that describes the quantity of motion of a moving body. It is a vector quantity, meaning it has both magnitude and direction, and is calculated as the product of an object's mass and velocity.

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: 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 conserved quantity in isolated systems, making it crucial for analyzing collisions and other interactions. It's essential in understanding motion, force applications, and energy transformations in physical systems.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Mass must be a positive value, while velocity can be positive or negative depending on direction.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of momentum?
A: Momentum is measured in kilogram-meters per second (kg·m/s) in the SI system.

Q2: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.

Q3: What is the law of conservation of momentum?
A: In an isolated system, the total momentum remains constant unless acted upon by external forces.

Q4: How does momentum relate to force?
A: Force is equal to the rate of change of momentum (F = Δp/Δt), as described by Newton's second law.

Q5: Can momentum be negative?
A: Yes, since velocity can be negative (indicating direction), momentum can also be negative.
