In an impact like a car crash the work made by the impact force slowing down an moving object over a distance by deforming the crumple zone can be expressed as. W = Favg s (2) where. W = work done (J, ft lb) Favg = average impact force during deformation (N, lbf) s = deformation distance, crumple zone (m, ft) When a crumple zone deforms in

Soil texture, soil structure, and slope have the largest impact on infiltration rate. Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a
