Sandy soils usually have very high percolation rates, measured in the range of 1 to 8 inches or more per hour. That means sandy soils dry out very quickly, heat up very quickly and do not hold nutrients for very long. Silty soils, including loam, have moderate percolation speeds, ranging from 0.1 to 1 inch per hour.

The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it.. The frictional force can be expressed as. F f = μ N (1). where. F f = frictional force (N, lb). μ = static (μ s) or kinetic (μ k) frictional coefficient. N = normal force between the surfaces (N, lb) There are at least two types of friction forces
