1. What is Momentum?

Momentum is a fundamental concept in physics that describes the quantity of motion an object has. It is a vector quantity, meaning it has both magnitude and direction, and is calculated as 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 (kg)
• \( v \) — Velocity (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 calculations are essential in understanding collisions, conservation of momentum, and analyzing motion in physics. It's crucial for predicting the outcomes of interactions between objects.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be valid (mass > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of momentum?
A: The SI unit of 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: What is the law of 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.

Q4: How does momentum relate to force?
A: Force is equal to the rate of change of momentum (F = Δp/Δt).

Q5: What is impulse in relation to momentum?
A: Impulse is the change in momentum of an object when a force is applied over time (J = FΔt = Δp).
