1. What Is The Momentum Equation?

The momentum equation (p = m × v) calculates the momentum of a moving object, where momentum is the product of an object's mass and its velocity. Momentum is a vector quantity that describes the quantity of motion an object possesses.

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 calculation is fundamental in physics for understanding collisions, conservation laws, and motion dynamics. It's crucial in engineering applications, 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 greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is momentum measured in?
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: How does momentum relate to force?
A: Force equals the rate of change of momentum (F = Δp/Δt), as described by Newton's second law.

Q4: What is the 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.

Q5: Can momentum be negative?
A: Yes, since momentum is a vector, it can be negative when the direction of motion is opposite to the chosen positive direction.
