Impulse

Impulse is the total effect of a force acting over a time interval, found by integrating the force with respect to time. It equals the change in momentum of the object the force acts on.

\boldsymbol{I} = \int_{t_1}^{t_2} \boldsymbol{F} \, \mathrm{d}t

What the symbols mean

impulse vector, in newton seconds (\mathrm{N\,s})
force vector acting on the object, in newtons
start time of the interval, in seconds
end time of the interval, in seconds
time variable of integration, in seconds
