3.3 The Momentum Equation 3.3.1 Force Balance In deriving this physical law, we begin by considering the fluid element as described in Fig. 3.2 for mass conservation. Newton's second law of motion states that the sum of forces, which is acting on the fluid element, as illustrated in Fig....
"To linearize the given momentum equation, we assume that the perturbed variables ($\delta \rho$), ($\delta p$), ($\delta \mathbf{v}$), and ($\delta \mathbf{B}$) are small compared to their equilibrium values ($\rho_0$), ($p_0$), ($\mathbf{v}_0$), and ($\mathbf{B}...
Using the definition of impulse, the change in momentum of car 1 is given by Δp1=F1Δt, whereF1is the force on car 1 due to car 2, and Δtis the time the force acts (the duration of the collision). Intuitively, it seems obvious that the collision time is the same for both car...
Solution To determine the change in momentum, substitute the values for the initial and final velocities into the equation above. Δp=m(vf−vi)=(0.057kg)(58m/s−0m/s)=3.306kg⋅m/s≈3.3kg⋅m/sΔp=m(vf−vi)=(0.057kg)(58m/s−0m/s)=3.306kg⋅m/s≈3.3kg⋅m/s...

This equation is an analog to the definition of linear momentum as p = mv. Units for linear momentum are kg ⋅ m/s while units for angular momentum are kg ⋅ m2/s. As we would expect, an object that has a large moment of inertia I, such as Earth, has a very large angular ...
