Ch6 Momentum and forces in fluid flow_1
In the second chapter, we introduce the concepts of force, traction, and stress developing in a fluid consisting of a single chemical species. By invoking Newton's second law of motion for a material fluid parcel, we derive the Cauchy equation of motion for a compressible or incompressible ...
To determine the change in momentum, substitute the values for the initial and final velocities into the equation above. Δp=m(vf−vi)=(0.057 kg)(58 m/s−0 m/s)=3.306 kg⋅m/s≈3.3 kg⋅m/sΔp=m(vf−vi)=(0.057 kg)(58 m/s−0 m/s)=3.306 kg⋅m/s≈3.3 kg⋅m/...

Equation : The S.I. unit of linear momentum is kg m s-1. The direction of the momentum is the same as the direction of the velocity. Momentum can be resolve into vertical (y) component horizontal (x) component. 4 Impulse, Let a single constant force, F acts on an object in a ...
