The Impulse and Momentum Calculator is a specialized physics tool that calculates the relationships between impulse, momentum, force, and time in collisions and force applications. This fundamental concept in mechanics helps understand how forces change momentum and how momentum is conserved in collisions.
For more information about impulse and momentum, visit Wikipedia: Impulse and Wikipedia: Momentum.
Impulse is the change in momentum caused by a force applied over time, while momentum is the quantity of motion an object possesses. The impulse-momentum theorem connects these concepts, showing that impulse equals the change in momentum, which is crucial for analyzing collisions and force applications.
Impulse equals the change in momentum: J = Δp = m × Δv
Whether you're studying collision physics, analyzing impact forces, designing safety systems, or investigating momentum conservation, this calculator provides accurate impulse and momentum analysis for educational and professional applications.

p = m × v
J = F × t
J = Δp = m × Δv
Where p is momentum, m is mass, v is velocity, J is impulse, F is force, t is time, and Δp is change in momentum.
Impulse and momentum calculations use the fundamental relationship between force, time, and momentum change. The impulse-momentum theorem states that the impulse applied to an object equals the change in momentum of that object, providing a powerful tool for analyzing collisions and force applications.
The calculator can determine impulse from force and time, momentum change from mass and velocity change, or force from impulse and time. It handles various scenarios including collisions, force applications, and momentum conservation analysis.
Mass: Object mass affects momentum magnitude
Velocity Change: Difference between final and initial velocities
Force: Applied force magnitude
Time: Duration of force application
Impulse: Force × time = change in momentum
The calculator automatically handles unit conversions and provides step-by-step solutions. It can determine impulse, momentum change, force, and time relationships for various collision and force scenarios in educational and professional applications.
Given:
Step 1: Calculate momentum change
Δp = m × Δv = m × (v_final - v_initial)
Δp = 1500 × (0 - 20) = 1500 × (-20)
Δp = -30,000 kg⋅m/s
Step 2: Calculate impulse
J = Δp = -30,000 kg⋅m/s
Impulse = 30,000 kg⋅m/s (magnitude)
Step 3: Calculate average force
F = J / t = 30,000 / 0.1
F = 300,000 N = 300 kN
Final Answer
Impulse: 30,000 kg⋅m/s
Average Force: 300 kN
Car experiences 300 kN average force during collision
Given:
Step 1: Calculate momentum change
Δp = m × Δv = m × (v_final - v_initial)
Δp = 0.5 × (8 - (-10)) = 0.5 × 18
Δp = 9 kg⋅m/s
Step 2: Calculate impulse
J = Δp = 9 kg⋅m/s
Step 3: Calculate force
F = J / t = 9 / 0.02
F = 450 N
Final Answer
Impulse: 9 kg⋅m/s
Force: 450 N
Ball experiences 450 N force during bounce
⚡ Did you know? Airbags work by increasing the collision time, which reduces the average force experienced by passengers. This is a direct application of the impulse-momentum theorem!
