1. What is a Momentum and Impulse Calculator?

Definition: This calculator computes momentum (p) and impulse (J) using fundamental physics formulas.

Purpose: It helps students, engineers, and physicists understand and calculate these important physics concepts.

2. How Does the Calculator Work?

The calculator uses the formulas:

Where:

• \( p \) — Momentum (kilogram meters per second, kg m/s)
• \( m \) — Mass (kilograms, kg)
• \( v \) — Velocity (meters per second, m/s)
• \( J \) — Impulse (Newton seconds, N s)
• \( \Delta p \) — Change in momentum (kg m/s)

Explanation: Momentum is the product of mass and velocity, while impulse equals the change in momentum.

3. Importance of Momentum and Impulse

Details: These concepts are fundamental in understanding collisions, rocket propulsion, and many mechanical systems.

4. Using the Calculator

Tips: Enter mass and velocity to calculate momentum. Optionally enter impulse to calculate change in momentum.

5. Frequently Asked Questions (FAQ)

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

Q2: How is impulse related to momentum?
A: Impulse equals the change in momentum (J = Δp).

Q3: Can momentum be negative?
A: Yes, momentum is a vector quantity so direction matters. Negative values indicate opposite direction.

Q4: What's a practical example of impulse?
A: Airbags increase the time of impact (impulse) to reduce force during a collision.

Q5: How does mass affect momentum?
A: Momentum is directly proportional to mass - double the mass doubles the momentum at same velocity.
