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.
In other words, if no force acts on an object it will maintain a constant velocity (for an object at rest that velocity is equal to zero). With the first law of motion, Newton established the existence of a frame of reference for which his other laws of motion are applicable, called the inertial frame of reference. An inertial frame of reference is one in which the observer is moving at constant velocity (which includes being stationary).
