Chandrasekhar describes a dynamical version of this that moving bodies experience due to loss of energy from gravitational interactions with mass in space.
In laminar flow, sixty-four over over the Reynolds number gives Darcy's dimensionless factor of this quantity. Chandrasekhar describes a dynamical version of this that moving bodies experience due to loss of energy from gravitational interactions with mass in space. Drag is sometimes known as the air type of this phenomenon, and Coulomb names its simplified dry type. Its coefficient is symbolized mu, and this force occurs in kinetic and static varieties. For 10 points, name this force that opposes motion when two objects rub against each other.
