Impulse vs Time Duration
Formule
## 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.
Exemple Résolu
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
Questions Fréquentes
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.
