1. What is Momentum?

Momentum is a measurement involving the motion of an object in motion and is calculated by multiplying the mass of the object by its velocity. It is a vector quantity, meaning it has both magnitude and direction.

2. How Does the Calculator Work?

The calculator uses the momentum formula:

Where:

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

Explanation: The greater the mass or velocity of an object, the greater its momentum will be.

3. Importance of Momentum Calculation

Details: Momentum is fundamental in physics, particularly in understanding collisions, conservation laws, and motion. It's crucial in fields like engineering, vehicle safety design, and sports science.

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: The standard SI unit is 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 event equals the total momentum after the event.

Q4: Can momentum be negative?
A: Yes, since velocity can be negative (indicating direction), momentum can be negative too.

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