Congressman Barney Frank - Representing the 4th District of Massachusetts
Because of the discovery of poisonous biological agents, mail sent to Congress via the U.S. Postal Service now goes through additional security protocols that can delay its delivery to individual Congressional offices by several weeks or more in some cases. As a result, anyone who sends, or has recently sent, a letter to my Washington office could experience a significant delay before receiving a response. Therefore, if you require swift assistance, and you are a resident of the Fourth Congressional District, I suggest that you contact me by telephone or email. All bulk materials should be sent to my Newton Office. You have my assurances that I will respond to every constituent request as expeditiously as possible. My three District Offices, located in New Bedford, Newton and Taunton, continue to receive mail normally. Click here for contact information. ... [Read More]
Newton's Second Law of Motion
Sir Isaac Newton first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1686. His second law defines a force to be equal to the differential change in momentum per unit time as described by the calculus of mathematics, which Newton also developed. The momentum is defined to be the mass of an object m times its velocity v . So the differential equation for force F is: ... The important fact is that a force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways. The velocity, force, acceleration, and momentum have both a magnitude and a direction associated with them. Scientists and mathematicians call this a vector quantity . The equations shown here are actually vector equations and can be applied in each of the component directions . ... [Read More]

EIA kid's page - Newton's Second Law of Motion
F = ma : Newton's second law of motion states that the net force acting on an object equals the product of the mass ( m ) times the acceleration ( a ) of the object. The direction of the force is the same as that of the acceleration. ... Newton's Second Law of Motion: F=ma ... EIA Main Home Page ... [Read More]
Ask A Scientist -Weekly Posting
Dear John,Atoms are governed by quantum mechanics, so you have to expect them tobehave strangely by Newtonian standards.Consider the hydrogen atom. This is the simplest atom, consisting of aproton and an electron. When the electron is captured by the proton, itwill "see" a large (infinite) number of energy levels. If it gives upenough energy to be captured in a high energy level, it can then lose moreenergy by emitting photons as it descends to lower energy level. Finally itarrives at the lowest energy level. This is one place where quantummechanics differs from classical mechanics -- the moon can continuouslyreduce the radius of its orbit about the earth until it finally crashes intothe earth.When the electron reaches its lowest energy state, it is far from the edgeof the proton -- the radius of its orbit is about 1000 times larger than theradius of the proton. The Heisenberg Uncertainty Principle (HUP) then saysthat if the position of the electron is well determined by being in the ... [Read More]
