Impulse Formula:
From: | To: |
Definition: This calculator computes the impulse (J) of an object based on its mass and velocity using the formula J = m × v.
Purpose: It helps physics students and professionals calculate impulse when the mass and velocity of an object are known.
The calculator uses the formula:
Where:
Explanation: Impulse is the product of an object's mass and its velocity, representing the change in momentum when starting from rest.
Details: Impulse calculations are crucial in physics for understanding collisions, rocket propulsion, and other force-time interactions.
Tips: Enter the mass in kilograms and velocity in meters/second. All values must be positive numbers.
Q1: What are the units of impulse?
A: Impulse is measured in Newton-seconds (N s), which is equivalent to kg·m/s.
Q2: How is this different from momentum?
A: Impulse equals the change in momentum. This formula calculates impulse when starting from rest (initial momentum = 0).
Q3: Can I use this for objects already in motion?
A: This calculates total impulse from rest. For objects in motion, you'd need to calculate change in velocity (Δv).
Q4: What's a typical impulse value?
A: Values vary widely. Example: A 1kg ball moving at 10m/s has 10 N s impulse.
Q5: How does impulse relate to force?
A: Impulse equals force multiplied by time (J = F × t). This formula is a special case when starting from rest.
