Why are we still teaching Newtonian physics if it's "false"?
2014年12月24日 · In other words Newtonian physics are an accurate enough approximation to the more precise theory, special relativity. Lets not forget that Newtonian physics is accurate enough to take us to the moon! Other than that some conservation laws from Newtonian physics carry on to the rest of physics, for example conservation of energy and momentum.
Newtonian gravity vs. general relativity: exactly how wrong is …
It would have been natural, but not justified, to assume then that Newtonian gravity was exactly correct. This is the sense in which GR "overthrew" Newton. These days physicists tend to think we know better where the limits of our theories are. Our "effective theories" have built-in breaking points which tell us where to look for new physics.
Recommendations for good Newtonian mechanics and kinematics …
Young and Freedman, Sears and Semansky's University Physics. This is an excellent book, with pretty much every concept on covered in first year university level physics. Within the mechanics section ($\simeq$ 500 pages)(which I presume the OP wants), it has chapters on. Motion along a straight line; Motion in 2D and 3D; Newton's laws of motion
Can a black hole be explained by Newtonian gravity?
2021年7月4日 · Newtonian physics predicts that light travelling close to a massive body has a trajectory that curves by about half the amount predicted by GR. Even stranger effects are predicted close to the black hole including that light can orbit at …
What is the difference between Newtonian and Lagrangian …
It is all about Frame of reference. In Newtonian physics you stand at a point and watch something move in relation to the stationary observation point based on forces applied. In lagrangian physics you are the something moving that experiences the forces. Reynolds transport theorem relates the two frames of reference.
When does Newtonian physics fail? - Physics Stack Exchange
2024年4月12日 · When does Newtonian physics fail? The answer by Zo the Relativist to the question How accurate is Newtonian Gravity? includes the statement: The key point is that Newtonian physics fails when, rou...
What is the relation between General Relativity and Newtonian …
Also in Newtonian Physics time is treated as a variable which is independent of space coordinates, whereas in GR time may not be de-attached from space, being time part of the coordinate system (x,y,z,t) and thus the term space-time. The real relationship between Newtonian Physics and GR is that every case of Newtonian Physics can be proved ...
Does Newtonian mechanics predict the bending of the course of …
Yes, Newtonian physics does predict the bending of light by gravity. In fact, using Newtonian theory only, a geologist in 1783 noted that if the sun were 500 times larger in diameter but with the same density, light would not be able to escape it. That is, it would be a black hole.

2021年1月4日 · $\begingroup$ Re "fog"/"flight": I don't think seeing into space was necessary for the beginnings of modern physics (given the stipulation that Newtonian physics would have been discovered). The discovery of electromagnetism (and hence special relativity), electrons, photons, and nuclei (and hence quantum mechanics) in the late 1800s and early ...
Newtonian physics vs Special relativity - what is the most "relative ...
Physics occurring in one spacecraft traveling fast (at a uniform speed) is the same as physics in another spacecraft "standing still". In fact, the whole point is that these words - traveling fast and standing still - are relative.
