Re: Impulse



Talk them through it qualitatively/semi-quantitatively:

Since acceleration is the time rate of change of velocity . . .
Acceleration times time = velocity change. . . .
multiply both sides by mass and use F=ma. . . .

The Impulse momentum theorem is the quantification of the above.

Hi
What's a good way to describe Impulse? The integral of F.dt is not
working for me with my students.
