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.
The first law of motion postulates the existence of at least one frame of reference called a Newtonian or inertial reference frame, relative to which the motion of a particle not subject to forces is a straight line at a constant speed. Newton's first law is often referred to as the law of inertia.
