Impulse Formula:
From: | To: |
Impulse is the product of the average force acting on an object and the time during which it acts. It equals the change in momentum of the object and is measured in Newton-seconds (N·s).
The calculator uses the impulse formula:
Where:
Explanation: This formula calculates the impulse by multiplying the mass of an object by its change in velocity, which equals the change in momentum.
Details: Impulse calculation is crucial in physics for understanding collisions, analyzing forces in impact situations, and solving problems related to momentum conservation.
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 Newton-seconds (N·s), which is equivalent to kg·m/s.
Q2: How is impulse related to force?
A: Impulse equals the product of force and time (J = F × Δt), and also equals the change in momentum (J = Δp = m × Δv).
Q3: Can impulse be negative?
A: Yes, impulse can be negative if the change in velocity is negative, indicating a decrease in momentum.
Q4: What's the difference between impulse and momentum?
A: Momentum is a quantity of motion (p = m × v), while impulse is the change in momentum (J = Δp).
Q5: How is impulse used in real-world applications?
A: Impulse principles are used in designing safety features like airbags and crumple zones in vehicles, sports equipment, and analyzing collisions in physics.
