General Physics is the study of matter, energy, and how they interact. It is one of the most important branches of science. Science describes how matter works, changes, and forms. It focuses on the tiniest particles in the universe. Physics has a profound impact on our lives every day.

History of physics
The name physics comes from the Greek word φσις (Physica), meaning “nature.” The many scientific laws, which are statements describing occurrences that have been repeatedly verified and proven, spring to mind while thinking of physics. This is an essential concept in general physics. To create these rules and explain how our universe works, physicists conduct endless experiments. These laws (like gravity and Newton’s laws of motion) have been thoroughly tested and can be used to anticipate how other things will behave.
The concept of physics, technology and society has been around for a very long time now. Ancient Greeks are the “fathers” of early physics, and Socrates, Plato, and Aristotle are some of the most well-known people in this group. People like Copernicus, Galileo and Newton came up with General physics during the period of the 1500s and 1600s. A lot of important scientific discoveries were made during this time period as people learned more and more about our world.
During the Scientific Revolution, we learned a lot of the things we take for granted now. There was a time when Copernicus proved that the earth moves around the sun, not the other way around. When Galileo made his very own telescope, he made many astronomical discoveries, like sunspots and planetary satellites, that he couldn’t have made without the telescope. Isaac Newton, who you’ll learn a lot about in your physics class, is a big part of the history of physics. He is best known for his three laws of motion and the law of universal gravitation. It’s also said that Newton came up with calculus.
Before the discovery of General physics, people thought that physics was the same as natural philosophy and chemistry mixed with a little maths, a little bit of biology and a lot of other things. Before the scientific revolution in the Renaissance, there were no limits on how far people could go with their research into the field.
Contribution made by various physicists
Bhaskaracharya
He proposed the concept of instantaneous motion, talked about gravitational laws and gave the concepts of calculus.
Galileo Galilei
He proposed the concept of acceleration, discovered the law of inertia, invented the gaseous thermometer and contributed to astronomy.
Issac Newton
He invented the binomial theorem for non-integer powers, gave the universal law of gravitation, and found out about the spectrum of white light.
Johannes Kepler
He gave the three laws of planetary motion and established geometric optics.
Robert Hook
- He was the designer of Gregorian
- Reflecting Telescope
Archimedes
He was the inventor of the catapult, a system made of a combination of pulleys, and proposed the concept of buoyant force.
Daniel Bernoulli
He worked in the field of fluid mechanics. He contributed to the works of calculus, probability, the principle of vibrating strings and applied mathematics. He established mathematical Physics.
Lord Kelvin
He had a major contribution in developing the concept of energy conservation which was already proposed by that time. He also brought forward the concept of Absolute Temperature. He also formulated the second law of thermodynamics with Sadi Carnot’s help.
Rudolph Clausius
He discovered the second law of thermodynamics. He discovered entropy on the basis of work done by Carnot And Kelvin. He also contributed to the field of the kinetic theory of gases.
John Dalton
He proposed the very first atomic theory in the modern world of science. He also proposed a theory related to colour blindness.
Conclusion
In this General Physics study material, we learned an overview of General physics and understood different aspects of it. Physics is a branch of science that explains physical phenomena. The workings of physics take on an intriguing new dimension. The goal of physics is to explain how everything around us works, from the tiniest charged particles to humans, automobiles, and spacecraft in motion. Basically, physics is divided into two parts, such as microscopic physics and macroscopic physics. Physics has different branches like optics, mechanics, thermodynamics, quantum mechanics, electromagnetism, etc. Physics can make substantial contributions to new technology through theoretical breakthroughs.
