Web2. Conservation of Momentum: Newton’s second law is simply the law of conservation of momentum. It states that the time rate of change of momentum of a system of particles is equal to the sum of external forces acting on that body. d Σ=Fi {MV} (3.11) dt where M =ρδδxz is the mass of the fluid parcel (in two dimensions, ie mass per unit WebMar 27, 2024 · If the gate is 1m wide, you'll need a certain force X to keep the gate closed. If the gate is 2m wide, you'll need 2X. Without the width of the gate, you'll have to find F …
