There may also be frequent falls. Body stiffness in the arms or legs, or tremors may also occur. Parkinson's mask (blank stare, emotionless look on face), stooped posture, drooling and runny nose may be present. REM Sleep Behavior Disorder (RBD) is often noted in persons with Lewy Body Dementia.
The newton (abbreviation and symbol: N) is the unit of force in metric system (SI), named after Isaac Newton. The newton is equal to the amount of force needed to accelerate a one kilogram mass at a rate of one meter per second squared. 1 newton (N) = 0.224808943 pounds force (lbf) = 0.101971621 kilogram-force (kgf) Report an error on this page.
The units of lift in the lift equation can be confusing because the English unit of pound represents force when representing weight, while kilogram is the metric unit of mass (newton is the unit of force). The conversion factor of 1 kilgram = 2.2 pounds, therefore converts the units of mass to force. The lift equation is L = Â½ Ï S V 2 CL where L is lift, S is area, V is airspeed, and CL is the lift coefficient. After unit analysis, lift is in units of kgÂ·m/s2 = newtons, or slugÂ·ft/s2 = pounds-force.
