And some may have temporary behavior problems due to stress. For example, the birth of a sibling, a divorce, or a death in the family may cause a child to act out. Behavior disorders are more serious. They involve a pattern of hostile, aggressive, or disruptive behaviors for more than 6 months. The behavior is also not appropriate for the child's age.
Fundamental Ambiguity in the Definition of Vertical Motion Geoffrey Blewitt Mackay School of Earth Sciences and Engineering, University of Nevada, Reno, USA. Abstract. Vertical motion is generally described as motion normal to some defined horizontal surface or family of surfaces. Such a surface can be con-structed geometrically or gravitationally.
A vertical shift is when the graph literally moves vertically, up or down. The movement is all based on what happens to the y-value of the graph. The y-axis of a coordinate plane is the vertical axis. When a function shifts vertically, the y-value changes. The x-value stays the same, while the y-value changes the amount of the shift. If it shifts up, then we add the value to the y-term.
