Is it correct that the two ways that force can be 'applied' are via an Impulse or Work? I know that force is defined as dp/dt, but how is force, mathematically, applied to a body? How is the dp/dt 'added in' to the behavior of the body, if that makes sense?

Ok, I'm understanding more. Could you explain how the dt's cancel out when dp/dt * v dt becomes dp * v? Are the differentials considered as numbers in these manipulations? Thanks for your reply.

I'm an undergrad who has just completed the standard calculus sequence (1, 2, and multivariable). I've done well in the courses, however, things like the following, which is a derivation of kinetic energy, still confuse me: Taken from here. I want to understand the symbolic...
