In fields such as fluid dynamics and solid mechanics, it is not feasible to follow the motion of individual atoms or molecules. Instead, the materials must be approximated by a continuum in which there is a particle or fluid parcel at each point that is assigned the average of the properties of atoms in a small region nearby. In particular, it has a density ρ and velocity v that depend on time t an… WebBy taking the derivative of both sides with respect to time and multiplying both sides by m i, the mass of particle i, we obtain p → ˙ i = ω × p → i Now we simply note that if F → i denotes the net force on particle i, then Newton's Second Law gives F → i = p → i ˙ so that
