Impulse Formula:
From: | To: |
Impulse calculation determines the change in momentum of an object, calculated as the product of mass and change in velocity. It represents the effect of a force acting over a time interval.
The calculator uses the impulse formula:
Where:
Explanation: The formula calculates the impulse by multiplying the object's mass by its change in velocity, representing the change in momentum.
Details: Impulse calculation is crucial in physics and engineering for analyzing collisions, understanding force-time relationships, and designing safety systems.
Tips: Enter mass in kilograms and change in velocity in meters per second. Both values must be valid (mass > 0).
Q1: What is the unit of impulse?
A: Impulse is measured in kilogram meters per second (kg·m/s), which is equivalent to Newton-seconds (N·s).
Q2: How is impulse related to force?
A: Impulse equals the integral of force with respect to time (J = ∫F dt), representing the total effect of a force over time.
Q3: What's the difference between impulse and momentum?
A: Impulse is the change in momentum (J = Δp), where momentum is the product of mass and velocity (p = mv).
Q4: Can impulse be negative?
A: Yes, impulse can be negative if the change in velocity is negative, indicating a decrease in momentum.
Q5: How is impulse used in real-world applications?
A: Impulse calculations are used in automotive safety (airbags, crumple zones), sports equipment design, and impact analysis.
