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.
Calculate the force required to accelerate an 8 pound wagon that is moving at 7 m/s2. 1  First, convert all your units to SI. 2  One pound is equal to .453 kg, so you'll need to multiply that value by your 8 pounds to determine the mass. 3  Multiply your new value for the mass (3.62 kg) by your acceleration value (7 m/s 2). Remember, 10 N is equal to 9.8 kg. 2  So, convert Newtons to kg by dividing by 9.8 kg. 3  Your new kg value should be 10.2 kg for the mass. 4  Multiply your new mass value (10.2 kg) times the acceleration (2.5 m/s 2).
