Important to notice Recognize neonates with different gestational age(GA) General care for the neonates Special risks of the prematures and LBWI Importance of the initial examination after birth
The causes of acceleration of a system--The first law of motion states that zero total force exists when the system has a constant velocity; a nonzero total force on the system causes its acceleration
