1. What is Momentum?

Momentum is a measurement involving the motion of an object in motion and its resistance to stopping. It is equal to the product of an object's mass and velocity.

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 depends on both its mass and velocity. Doubling either the mass or velocity will double the momentum.

3. Importance of Momentum Calculation

Details: Momentum is a fundamental concept in physics that helps in understanding collisions, motion, and the effects of forces on objects.

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 for momentum is kilogram meters per second (kg·m/s).

Q2: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum measures the quantity of motion, incorporating both mass and 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, momentum can be negative when the velocity is negative (indicating direction opposite to the chosen coordinate system).

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