# General Physics Reading Questions All Chapters

1990 words - 8 pages

Textbook Sections that I read: 2.1-3
Important Concepts:
• An interaction between two objects can be described and measured in terms of two forces. The force is a push or either a pull.
• There are two types of forces. #1 is a long range force and this force does not require the objects involved to be touching each other. An example of this is when you are holding a magnet away from a refrigerator and you are able to feel the magnetic pull. #2 is a contact force and this occurs only when the objects are touching one another.
• A vector in physics is another name for a force. All vectors have a direction in space and magnitude as well. Both ...view middle of the document...

The net force is the vector sum of all the forces that are acting on the object.
• Newton’s first law says that an object acted on by zero net force moves in a straight line with constant speed or it remains at rest if it was at rest.
• Velocity vector is a measurement of both speed and the direction of an objects motion.
• There is no force required to keep an object in motion as long as there are no forces that oppose its motion.
• Inertia means resistance to changes in velocity. Newton’s first law can also be called the law of inertia.
Explain the need for automobile seat belts in terms of Newton’s first law. Newton’s first law is an object in motion tends to stay in motion unless acted on by an opposing force. A car and seatbelts are connected together where the car goes the seatbelts go. The people in the car are not connected to the car. That is why they must be strapped in by the seatbelts. If the car had an accident of slammed on brakes really hard everyone would stay in motion that the car was in. Because the seatbelts are there to keep people in the same motion in the car it keeps a lot of people from being slung through the windshield.
A freight train consists of an engine and several identical cars on level ground. Determine whether each of the statements is correct or incorrect and explain why. (a) If the train is moving at constant speed, the engine must be pulling with a force greater than the train’s weight. False the engine would have to be pulling with the same force as the trains’ weight. (b) if the train is moving at constant speed, the engine’s pull on the first car must exceed that car’s backward pull on the engine. True, if the engines pull did not exceed the backward pull of the first car the weight of the other cars would cause the train to not be able to maintain constant speed. (c) If the train is coasting, its inertia makes it slow down and eventually stop. False, the friction of the trains wheels and tracks would be what caused it to slow down.
Reading Assignment #3: Newton’s Third Law
Textbook Sections that I read: 2.5
Important Concepts:
• Every force is part of an interaction between two objects and each of those objects exerts a force on the other. These forces are called an interaction pair; each of these forces is partners with one another.
• Newton’s third law of motion says that interaction partners always have the same magnitude and are in the opposite direction.
• Interaction partners are always of the same type.
• All the parts of an object make up the system.
• All the interactions that affect the system must be either internal or external.
• To find the net force on the system, ignore all the internal forces and add the external forces.
If a wagon starts at rest and pulls back on you with a force equal to the force you pull on it, as required by Newton’s third law, how is it possible for you to make the wagon start...

4926 words - 20 pages began to speak, the dog started to bark. For the duration of the entire conversation, the dog kept yapping. In the brief conversation Lindemann only asked a few questions of Heisenberg, one of which was what books he had been reading. Heisenberg responded with Weyl’s Space, Time and Matter, through the noise of the dog Lindemann closed the conversation with, "In that case you are completely lost in mathematics." Rejected by Lindemann

Modern geometry has multiple strong bonds with physics, exemplified by the ties between pseudo-Riemannian geometry and general relativity. One of the youngest physical theories, string theory, is also very geometric in flavor. While the visual nature of geometry makes it initially more accessible than other parts of mathematics, such as algebra or number theory, geometric language is

### Good Study Habbits

1658 words - 7 pages taking things too far. 3. Morning Review. Wake up a half hour earlier and spend that time reading from your textbook. If you’ve already read the chapters, spend the time rewriting the key concepts into a notebook. A half-hour out of your day in the morning probably won’t create a huge impact on your schedule, yet over the entire term it can be invaluable in boosting your understanding. 4. Link Courses to Daily Life. Spend some time each week

### History of Physics

1348 words - 6 pages History of Physics Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics

### Summary of chapters: Labor cost, supply and demand, and utility

377 words - 2 pages Throughout reading the first four chapters, I realized that every single roll (component) and system has to be balanced in order to form the market, the economy. So to create a market, something has to be produced to sell, and somebody has to purchase what has produced. Before producing a product, one must resolve three critical questions about the use of its scarce resources: What, how, and for whom to produce. Then to produce a product, first

On April 18, 1955, at the age of seventy-six, Albert Einstein passed away of a ruptured aortic aneurysm, at 1:15 in the morning, in Princeton Hospital. The nomination for the 20th Century Genius Award goes to Albert Einstein; he was the greatest scientist of all time. His ideas, and works, are a reflection

May the Lord grant that each of you will find rest in the home of another husband." As for the word choice, in the sections one to four I couldn't find the meaning of "ephah." I even looked it up in the dictionary and still had no luck Overall the theme of these chapters was foggy. I guess that I must finish reading it
