What is Physics 1: Definition and 115 Discussions

Physics (from Ancient Greek: φυσική (ἐπιστήμη), romanized: physikḗ (epistḗmē), lit. 'knowledge of nature', from φύσις phýsis 'nature') is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest. Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy, but during the Scientific Revolution in the 17th century these natural sciences emerged as unique research endeavors in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in academic disciplines such as mathematics and philosophy.
Advances in physics often enable advances in new technologies. For example, advances in the understanding of electromagnetism, solid-state physics, and nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

    Will I Transfer to UIUC Engineering with a C in Physics?

    Will I be still able to transfer to UIUC school of engineering? I have talked to the Illinois advisor, he said as long as you have 3.0gpa. But would one C derail my chances?

    Didn't learn simple harmonic motion in physics 1, will this hurt me?

    I took calc-based physics 1 last semester, but since it was at a community college, I don't think we went as far as the 4 year universities went. We skipped over simple harmonic motion. Will this hurt me later on, when I go to mid-level and upper-level physics courses at the 4-year university...

    Schools Physics 1 (University Physics) Online

    Due to time restraints and the fact that my university won't let me take classes at a two year (But won't offer it during the summer themselves -_-) I need to find an accredited four year+ school that offers Physics 1 online over the summer. I've been looking around but haven't found anything as...

    Who wants to grade my test? (physics 1, simple for physics buffs)

    Just took my 2nd physics test of the semester. didn't do so well on the first one, so I'm kind of anxious to see how i did on this one(our professor let's us keep the test and we turn in the scantron sheet). honestly, i have no clue how well i did. i know its a lot to ask, but if anyone wants to...

    B in physics 1 (basic freshman mechanics) = bad?

    ok, I am of one of those good universities and going to be a physics/math major. I was taking matter and Interaction 1 ( mechanics course honors for freshman), I was doing well in the course attaining very well low As around 88-90, the point drop is significant as 1 question weighs 25 points and...
