Impulse

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Impulse, abbreviated as I, is the force applied to an object over time.

Impulse formula

 $$\large{ I = F \; \Delta t }$$ $$\large{ I = m \; \Delta v }$$

Where:

 Units English Metric $$\large{ I }$$ = impulse $$\large{lbf-sec}$$ $$\large{N-s}$$ $$\large{ F }$$ = force $$\large{lbf}$$ $$\large{\frac{kg-m}{s^2}}$$ $$\large{ m }$$ = mass $$\large{lbm}$$ $$\large{kg}$$ $$\large{ \Delta t }$$ = time change $$\large{sec}$$ $$\large{s}$$ $$\large{ \Delta v }$$ = velocity change $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
