Impulse vs Time Duration
Fórmula
Impulse
Impulse is the product of a force and the time interval over which it acts, equal to the change in momentum.
Formula
J = F * delta_t = delta_p
This is the impulse-momentum theorem.
Ejemplo Resuelto
A bat exerts an average force of 100 N on a ball for 0.5 seconds.
- 01J = F * t
- 02J = 100 * 0.5
- 03J = 50 N·s
Preguntas Frecuentes
How is impulse related to momentum?
Impulse equals the change in momentum: J = delta_p = m * delta_v. This is the impulse-momentum theorem.
Why do airbags reduce injury?
Airbags increase the time of collision, reducing the average force while delivering the same impulse (same momentum change).
What are the units of impulse?
Newton-seconds (N·s), which are equivalent to kg·m/s, the same units as momentum.
