Define Newton or SI unit of force
Newton: N (after Sir I. Newton, 1642-1727): The derived SI unit of force, stated as the force needed to give a mass of 1 kg of an acceleration of 1 m/s2; it therefore has units of kg m/s2.
Coanda effect: The effect which points out that a fluid tends to flow all along a surface, instead of flowing via free space.
