Pursuing the Physics Course Online becomes an option when one seeks to further his/ her studies and does not have ample time to visit school on a day to day basis. The MIT Department of Physics has been a national resource since the turn of the 20th century and a leading school in various fields. The Physics Course Online is taught through lecture notes, projects and examples, image galleries, selected lecture notes, projects (no examples), multimedia content, assignments and solutions, exams and solutions, OCW Scholar, assignments (no solutions), exams (no solutions), study groups and online textbooks.

In Conceptual Physics Answers, gravity can be defined as a force that binds together progressively larger structures from star to galaxy to super cluster and may be drawing them towards the great attractor. The force not only holds you on earth, but also reaches out across intergalactic space according to Conceptual Physics Answers. Engineering in Kenya has more articles.
Physicists on Gravitation for Conceptual Physics Answers
Physicists like to study seemingly unrelated phenomena to show that a relationship can always be found if they are examined closely enough. This search for unification has been going on for centuries. For example, in 1665, Isaac Newton made a simple and yet very significant contribution to physics when he showed that the force that holds the moon in its orbit is the same force that makes an apple fall.
We take this so much for granted now that it is not easy for us to comprehend the ancient belief that the motions of earth bound bodies and heavenly bodies were different in kind and were governed by different laws according to Conceptual Physics Answers.
Newton concluded that not only does earth attract an apple and the moon but every body in the universe attracts every other body: this tendency of bodies moving towards each other is called gravitation in Conceptual Physics Answers. Newton’s conclusion takes a little getting used to because the familiar attraction of earth for earthbound bodies is so great that it overwhelms the attraction that earthbound bodies have for each other.
For example, earth attracts an apple with a force magnitude of about 0.8N. You also attract a nearby apple and it attracts you according to Conceptual Physics Answers, but the force of attraction has less magnitude than the weight of a spec of dust. Quantitatively, Newton proposed s force law that we call Newton’s law of gravitation which states that: – every particle attracts any other particle with a gravitational force whose magnitude in Conceptual Physics Answers is given by;Read More
Conceptual Physics deals with the theoretical part of physics. It entails the basics that any good physician should have in order to dig deeper into more serious physics. The Bernoulli’s Principle in Conceptual Physics was formulated by Bernoulli, who obtained a relation between the pressure and velocity at different parts of a moving incompressible fluid. If the viscosity is negligibly small, there are no frictional forces to overcome. Hence the work done by the pressure difference per unit volume of a fluid flowing along a pipe steadily is equal to the gain in kinetic energy per unit volume plus the gain in potential energy per unit volume according to the Bernoulli’s principle.

Physical science experiments range from simple to complex ones. Even the young children perform elementary experiments so as to learn about the world.
An experiment is a systematic trial and error process done with the aim of falsifying, verifying or establishing the soundness of a theory. Experiments differ significantly in their goal and scale, but always depend on repeatable method and rational analysis of the results.
A child can carry out fundamental experiments to comprehend the nature of gravity, whereas teams of scientists may take quit sometime of methodical investigation to advance the understanding of a phenomenon.
Majority of the physical science experimental labs are different from those used in biological or chemistry laboratories in structure and constituents.Read More
According to the history of computer in the computer generations, the first computer was build and designed by the English mathematical professor Charles Babbage during the year 1792 to 1871. The Babbage machine used a language that was purely mechanical and analytical engine. In fact, among the many computer machine developed it was one of the computers that had no operating system, which is it had to be managed manually. The discovery of the Babbage machine led to the development of less complex and easier machine during the generation of computer.Engineering in Kenya has more information.
The First generation Computer Generations
The first generation of computer, which was emerged during 1945 and 1955, used vacuum tubes and plug boards. During at around 1940s Howard Aiken at Harvard university, John Von Nerman of the institute of advanced study in Princeton, J Presper Eccert and Milliam Mancotey at the university of Pennsylvania and Konrad Zurse in Germany are the among those who succeeded in building calculating engines as the generation of computers developed. The first one used mechanical relays but was slow with cycles times measured in seconds; all programming was done in absolute machine language used by wiring up plug boards to the machine language basic function during the computer generation.
Programming languages were unknown during the computer generation; virtually all the problems were straight forward numerical calculating grounding out tables of sine’s, cosine and tangents. By early 1950’s punched card debuted and the routine of operating with computers improved. It was now possible during this generation of computers to write programs on cards and read them instead of plug board.
The second generation of computer, in the mid 1950’s, led to the introduction of the transistors that changed the computers radically. Computers became more reliable enough that they could be manufactured and be sold to buying customers who were mainly large corporations and universities. For the first time during the generation of computer there was separation between the designer, builders, operators, programmers and maintenance personnel. These types of computer which were mainly the mainframe type processed their jobs in batch system; this is whereby a collection of tray full of jobs and then processing them all at once. The computer that used to process batch jobs in this computer generation were IBM 1401 and IBM 7094
