1. What is Impulse?

Impulse is the change in momentum of an object when a force is applied over a time interval. It is calculated as the product of mass and change in velocity (J = m × Δv). Impulse is measured in kilogram meters per second (kg·m/s).

2. How Does the Calculator Work?

The calculator uses the impulse formula:

Where:

• \( J \) — Impulse (kg·m/s)
• \( m \) — Mass (kg)
• \( \Delta v \) — Change in velocity (m/s)

Explanation: The formula calculates the impulse by multiplying the object's mass by its change in velocity.

3. Importance of Impulse Calculation

Details: Impulse is important in physics for understanding collisions, rocket propulsion, and sports mechanics. It helps determine the force needed to change an object's momentum.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between impulse and momentum?
A: Impulse equals the change in momentum (J = Δp). Both are measured in the same units (kg·m/s).

Q2: Can impulse be negative?
A: Yes, impulse can be negative if the change in velocity is negative, indicating a decrease in momentum.

Q3: How is impulse related to force?
A: Impulse is also equal to the product of force and time (J = F × Δt), which shows how force applied over time changes momentum.

Q4: What are practical applications of impulse?
A: Airbags in cars, cushioning in packaging, and follow-through in sports all utilize impulse principles to reduce force impacts.

Q5: How does mass affect impulse?
A: For the same change in velocity, a larger mass will experience a greater impulse, requiring more force to achieve the same velocity change.
