Agate is good protective energy stone, especially for children, and is very calming and soothing. It also can help strengthen the body's connection to the earth.
The friction factor, f, is a dimensionless factor that depends primarily on the velocity u, diameter D, density Ï, and viscosity Î·. It is also a function of wall roughness which depends on the size Îµ, spacing Îµ' and shape of the roughness elements characterized by Îµ''.
exists and is an alternate of . Coefficient of Friction: Is a value between 0 and 1. It describes the degree of interaction between two surfaces. A higher coefficient of friction indicates that two surfaces in contact have a greater resistence. A lower coefficient of friction indicates that the two surfaces in contact have less resistence. For example: Soccer cleats on grass have a greater coefficient of friction than skates on ice. Coefficient of Friction: Is a value between 0 and 1. It describes the degree of interaction between two surfaces. A <i>higher coefficient of friction</i> indicates that two surfaces in contact have a <i>greater resistence</i>.
