1. What is Impulse?

Impulse is the product of the average force and the time interval during which the force is applied. It is equal to the change in momentum of an object and is measured in Newton-seconds (N·s).

2. How Does the Calculator Work?

The calculator uses the impulse formula:

Where:

• \( m \) — Mass of the object (kg)
• \( \Delta v \) — Change in velocity (m/s)

Explanation: The formula calculates impulse by multiplying the mass of an object by its change in velocity, which equals the change in momentum.

3. Importance of Impulse Calculation

Details: Impulse is crucial in physics for understanding collisions, impacts, and the effects of forces applied over time. It helps in analyzing safety mechanisms, sports dynamics, and vehicle crash testing.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between impulse and momentum?
A: Impulse is equal to the change in momentum of an object (J = Δp).

Q2: Why is impulse important in real-world applications?
A: It helps design safety features like airbags and crumple zones in cars by managing force over time to reduce impact.

Q3: Can impulse be negative?
A: Yes, impulse can be negative if the change in velocity is negative, indicating a decrease in momentum.

Q4: How does impulse relate to force?
A: Impulse is the integral of force with respect to time (J = ∫F dt), meaning it's the area under a force-time graph.

Q5: What are the units of impulse?
A: Impulse is measured in Newton-seconds (N·s) or kilogram-meters per second (kg·m/s).
