1. What is Impulse?

Impulse is the product of force and the time interval over which the force acts. It represents the change in momentum of an object when a force is applied over a period of time.

2. How Does the Calculator Work?

The calculator uses the impulse formula:

Where:

• \( Force \) — Applied force in Newtons (N)
• \( Time \) — Time duration in seconds (s)

Explanation: The impulse experienced by an object equals the force applied multiplied by the time interval during which the force is exerted.

3. Importance of Impulse Calculation

Details: Impulse calculation is crucial in physics and engineering for understanding momentum changes, collision analysis, and designing safety systems that reduce impact forces.

4. Using the Calculator

Tips: Enter force in Newtons (N) and time in seconds (s). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of impulse?
A: Impulse is measured in Newton-seconds (N·s), which are equivalent to kilogram-meters per second (kg·m/s).

Q2: How is impulse related to momentum?
A: Impulse equals the change in momentum of an object (J = Δp). This relationship is known as the impulse-momentum theorem.

Q3: Why is impulse important in safety design?
A: Safety devices like airbags and crumple zones increase the time over which a force acts, reducing the peak force while maintaining the same impulse.

Q4: Can impulse be negative?
A: Yes, impulse can be negative if the force is applied in the opposite direction to the object's motion.

Q5: How does impulse differ from work?
A: Impulse measures the effect of force over time (change in momentum), while work measures the effect of force over distance (change in energy).
