The Census Bureau defined the poverty level for a single individual as $11,888 in 2013. Many government assistance programs use different poverty measures. Starting in 2005, the American Community Survey is used here to estimate poverty rates.
I NTRODUCTION ï¢ Isaac Newton developed the First Law of Motion to demonstrate the properties of inertia. In doing so, Newton helped people understand movement and rest. ï¢ To illustrate this concept, our team demonstrated Newtonâs First Law of Motion for our EMPACTS project.
Three Laws of Motion. 1  Newton's First Law of Motion states that in order for the motion of an object to change, a force must act upon it, a concept generally called inertia. 2  Newton's Second Law of Motion defines the relationship between acceleration, force, and mass. Newton's Third Law of Motion states that any time a force acts from one object to another, there is an equal force acting back on the original object. If you pull on a rope, therefore, the rope is pulling back on you as well.
