... the ball is given a constant force M + πR2 ρ v0 /ε and torque Iω0 /ε in the time interval [0, ε] and we are looking for the limit when ε → 0. After the system is nondimensionalized, R, ν, ρ = 1 and only two parameters are left: M and I. If the ball has uniform density, M and I are determined by one ...

An Introduction to a Line Integral of a Vector Field
... One interpretation of the line integral of a vector field is the amount of work that a force field does on a particle as it moves along a curve. To illustrate this concept, we return to the slinky example3 we used to introduce arc length. Here, our slinky will be the helix parameterized4 by the func ...
