Impulse Equation:
From: | To: |
Impulse is a concept in physics that describes the effect of a force acting over time to change the momentum of an object. It is equal to the change in momentum of an object when a force is applied.
The calculator uses the impulse-momentum theorem:
Where:
Explanation: The calculator can compute impulse using either the force-time relationship or the mass-velocity relationship.
Details: Impulse is crucial in understanding collisions, rocket propulsion, sports mechanics, and any situation where forces act over time to change motion.
Tips: Enter either:
Q1: What are the units of impulse?
A: Impulse is measured in Newton-seconds (N·s) or kilogram-meters per second (kg·m/s).
Q2: How is impulse related to momentum?
A: Impulse equals the change in momentum (Δp) of an object when a force is applied.
Q3: Can I calculate impulse without knowing the time?
A: Yes, if you know the mass and change in velocity, you can calculate impulse without knowing the time.
Q4: What's the difference between impulse and force?
A: Force is an instantaneous measure, while impulse accounts for both the magnitude of force and its duration.
Q5: Where is impulse used in real life?
A: Applications include airbag systems, sports (like hitting a baseball), and spacecraft propulsion.
