Calculadora de impulso

Impulso a partir de la fuerza y el tiempo, J = F × t.

Introducción

Impulse Calculator — Impulse from force and time, J = F × t. Enter Force (N), Time (s) to get an instant, accurate result.

Fórmula

Impulse is calculated using the impulse-momentum theorem: J = F × t, where F is the net force applied and t is the duration of the force. Impulse equals the resulting change in momentum, Δp.

Paso a paso

  1. Enter the Force (N).
  2. Enter the Time (s).
  3. Click Calculate to see your result instantly.

Ejemplo del mundo real

Example: With Force (N) = 5, Time (s) = 3, the Impulse Calculator gives Impulse Ns: 15.

Preguntas Frecuentes

What is the impulse-momentum theorem?
It states that the impulse applied to an object (force multiplied by time) equals the change in that object's momentum: J = FΔt = Δp.
What units is impulse measured in?
Impulse has units of newton-seconds (N·s), which are dimensionally equivalent to kilogram-meters per second (kg·m/s), the units of momentum.
Why does impulse matter in collisions?
Impulse explains why extending the time of impact (like with airbags or padded surfaces) reduces the peak force experienced, since a smaller force over a longer time can produce the same impulse.
What inputs does the Impulse Calculator need?
You'll need to provide: Force (N), Time (s). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Impulse Calculator?
The Impulse Calculator applies the formula exactly as calculated — Impulse is calculated using the impulse-momentum theorem: J = F × t, where F is the net force applied and t is the duration of the force. Impulse equals the resulting change in momentum, Δp. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Impulse Calculator free to use?
Yes, the Impulse Calculator is completely free, requires no signup, and runs instantly in your browser.

Acerca de Calculadora de impulso

The Impulse Calculator uses a real, verifiable formula — Impulse is calculated using the impulse-momentum theorem: J = F × t, where F is the net force applied and t is the duration of the force. Impulse equals the resulting change in momentum, Δp. — so results are accurate every time, not an approximation.
