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, possessing both magnitude and direction.

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 momentum of an object is directly proportional to both its mass and velocity.

3. Importance of Momentum Calculation

Details: Momentum is crucial in physics for understanding collisions, conservation laws, and motion. It's used in 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 SI unit for momentum is kg·m/s (kilogram meter per second).

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

Q5: Can momentum be negative?
A: Yes, since momentum is a vector quantity, negative values indicate direction opposite to the chosen positive direction.
