1. What is Momentum?

Momentum is a measurement involving the motion of an object in motion and the mass of the object. It is a vector quantity, meaning it has both magnitude and direction. In physics, momentum is conserved in isolated systems.

2. How Does the Calculator Work?

The calculator uses the momentum equation:

Where:

• \( p \) — Momentum (kg m/s)
• \( m \) — Mass of the object (kg)
• \( v \) — Velocity of the object (m/s)

Explanation: The momentum of an object is directly proportional to both its mass and velocity. Doubling either mass or velocity will double the momentum.

3. Importance of Momentum Calculation

Details: Momentum is crucial in understanding collisions, explosions, and other interactions between objects. It's fundamental in fields like engineering, physics, and transportation safety.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum incorporates both the object's mass and its velocity.

Q3: What is the law of conservation of momentum?
A: In a closed system with no external forces, the total momentum before an interaction equals the total momentum after.

Q4: Can momentum be negative?
A: Yes, since momentum is a vector quantity, a negative value indicates direction opposite to the defined positive direction.

Q5: How does momentum relate to force?
A: Force equals the rate of change of momentum (Newton's Second Law: F = Δp/Δt).
