The center of gravity is defined as: a. The part of the skeleton composed of the bones of the vertebral column, ribs, and skull
b. A plane the passes through the midpoint of the body c. State of an object as a result of forces pushing on it d. Imaginary point through which the resultant force of gravity acts on an object
d. Imaginary point through which the resultant force of gravity acts on an object
Explanation:
Gravity acting on all particle points of the object, no matter how small they are. As a combination, the center of gravity would denote a single point which substitutes for all the gravity forces on the object.
A chair at rest on the floor has two forces acting on it its own weight that pulls it downward and the floor pushing upward on the chair, both of these forces are acting on it but the net force is 0, so the chair remains at rest and its velocity stays at 0.
Social psychologists utilize experimental techniques to study how people are influenced by groups. Health psychologists rely on experimentation and research to better understand the factors that contribute to wellness and disease.
