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.
(By definition, one newton is that amount of force that accelerates a kilogram of mass 1 m/sec 2. ). The acceleration of gravity is 9.8 m/sec 2. The weight of a body is the force exerted by the earth on the body and this force accelerates the body at a rate of 9.8 m/sec 2. Thus the gravitational force on a 1 Kg object must be a force of 9.8 newtons.
