Science Toys. Common Errors in English Usage. Ballistic Flight Equations. The study of model rockets, the flight of a baseball, or the "bend" of a soccer kick are excellent ways for students to learn the basics of forces and the response of an object to external forces. A ball in flight has no engine to produce continuous thrust and the resulting flight is similar to the flight of shell from a cannon, or a bullet from a gun.
This type of flight is called ballistic flight and on this page we present the equations that describe ballistic flight. Ballistic flight only occurs under the ideal conditions that weight is the only force acting on the object. There is no thrust and no aerodynamic drag acting on an object in ballistic flight. On Earth a baseball or a soccer ball generate a moderate amount of aerodynamic drag and the flight path is not strictly ballistic. For ballistic flight, the ball is normally inclined at some angle to the vertical (or horizontal) as it is launched. X = U0 * t -W = F = m a = m dV/dt dV/dt = - W/m = -g V = Vo - g t dy/dt = V = Vo - g t. Chemical Crayon. Paula Golden: Keep Science Fairs Alive. Science fairs, those time-tested incubators of future American scientists and engineers and a national fixture for generations, are in trouble.
Recent stories in major metropolitan newspapers across the country have reported that science fairs are being threatened with extinction when local sponsors drop out. In Los Angeles, the California Science Center is looking to find a sponsor for its annual California State Science Fair after a major corporate sponsor dropped out. Last year, the Irvine, Calif., Unified School District almost canceled its well-respected science fair because of lack of funding. A major Midwest paper recently sounded the alarm, noting that "cuts threaten these showcases for student inventions and scientific research.
Amen. Science fair funding cuts pose a national crisis, especially in light of sobering academic statistics that continue to show our kids running well behind students in China and a dozen other countries in science and math.

Some free college courses use the term massive online open course (MOOC). Benefits of Open Courses Free online college courses allow students to learn from home, a significant advantage for learners who prefer to eliminate a commute. In a free college course, learners can explore new academic topics without incurring high tuition costs.
