1. What Is The Momentum Formula?

The momentum formula (p = m × v) calculates the quantity of motion of a moving object, where p represents momentum, m is mass, and v is velocity. It is a fundamental concept in physics that describes how difficult it is to stop a moving object.

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: 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 calculations are essential in physics for understanding collisions, conservation laws, and motion dynamics. It's used in 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 greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What are the SI units for momentum?
A: The SI unit for momentum is kilogram-meter per second (kg·m/s).

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

Q3: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum incorporates both velocity and mass, representing the quantity of motion.

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, momentum can be negative when the velocity is in the opposite direction of the chosen coordinate system.
