I know that the work done in a closed system is 00 for this particular case. Also, I know that the work done is independent on the path traced but just the initial and final position. With these conditions, if a planet while revolving around the sun due to gravitational force goes fro...
Basic physics states that if there are no external forces at work, an object will always travel in the straightest possible line. Accordingly, without an external force, two objects traveling along parallel paths will always remain parallel. They will never meet. But the fact is, they do meet...
How much work is done in stretching the spring by 15 cm? Is this work dependent on the magnitude of force applied while stretching the spring? I am not sure if the work done would be just 0.5kx2 = 0.5 x 500 x 0.15[SUP}2[/SUP] = 5.625 J or one should use a more rigorous ...
The problems we are experiencing personally and collectively are a result of a false premise in science. The mind creates events, and if the mind is polluted by false beliefs, it creates invisible barriers to success that hold people back. These lead to struggle, unhappiness and excessive work...
Of all the sciences, physics is unique in that it can come to a broad consensus with math alone—very little tactile evidence required. Never has this been the case more than with dark matter. Though it's far more abundant than the matter we can see and feel, dark matter as we know ...

Finally if the author is writing about a subject in its current state, be sure that the sources are current. For example, studies done by Einstein in the early 20th century may not be appropriate if the writer is discussing the current state of knowledge in physics.A.Evaluate the sources ...
