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 its 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 equation shows that momentum is directly proportional to both mass and velocity. Doubling either 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 understanding motion in physics. It's used in various fields including engineering, sports science, and vehicle safety design.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers. The calculator will compute the momentum in kg·m/s.

5. Frequently Asked Questions (FAQ)

Q1: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of the velocity.

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

Q3: What is the principle 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: Can momentum be negative?
A: Yes, since momentum is a vector quantity, it can be negative when the direction of motion is opposite to the chosen positive direction.

Q5: 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.
