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.
It is thus possible for forces to act on an object, yet have the net force be zero. When evaluating the motion caused by forces acting on an object, remember to find the vector sum of those forces. Also included in Newton's First Law, though not explicitly, is the concept of inertia. Inertia is defined as the tendency of an object to remain at a constant velocity.
