1. What is Momentum?

Momentum is a fundamental concept in physics that describes the quantity of motion an object has. 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 formula:

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 crucial in understanding collisions, conservation laws, and motion dynamics. It's used in various fields including engineering, physics, and sports science to analyze and predict the behavior of moving objects.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers to calculate valid momentum.

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 a closed system with no external forces, the total momentum before a collision equals the total momentum after the collision.

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 of motion.

Q5: Can momentum be negative?
A: Yes, momentum can be negative as it's a vector quantity. Negative momentum indicates motion in the opposite direction of the defined positive direction.
