1. What is the Momentum Equation?

The momentum equation (p = m × v) is a fundamental formula in physics that calculates the quantity of motion of a moving object. Momentum is a vector quantity that depends on both the mass and velocity of an object.

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 equation shows that momentum is directly proportional to both mass and velocity. Doubling either mass or velocity will double the momentum.

3. Importance of Momentum Calculation

Details: Momentum is a conserved quantity in isolated systems, making it crucial for analyzing collisions, explosions, and other interactions between objects in physics and engineering applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

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 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 equals the rate of change of momentum (F = Δp/Δt), as described by Newton's second law.

Q5: What is impulse and how does it relate to momentum?
A: Impulse is the change in momentum and equals force multiplied by time (J = F × Δt = Δp).
