Learning the basics of physics might be hard if you don't have a strong enough foundation for the subject.
However, with these helpful tips and enough mathematical acumen, you will quickly be on your way to learning physics like a true academic..
This can also be called locality principle; (.
2) Causality principle: the future state depends only on the present state; (.
3) Covariance principle: the physics should be invariant under an arbitrary coordinate transformation; (.
4) Invariance or Symmetry principle: the spacetime is homogeneous; (.
5) Equi-probability .
Physics is the natural science that studies the matter and its motion and behaviour through space and time and that studies the related entities of energy and force..
The traditional branches of classical physics are Optics, Acoustics, Electromagnetics, and Classical mechanics.
With the rapid development of physics, the scope of the subject is growing so large that it is not possible to cover physics under the above branches..
Physics is the study of matter and its motion through space and time.
Albert Einstein was one of the most famous physicists.
With his powerful imagination and curious mind, he investigated challenging questions about things like the nature of light, the force of gravity, and time..
Gravity.
One of the easier concepts, gravity is a force of attraction and is simply the pull of the Earth.
Gravity is why things fall The Earth's gravitational force is also what gives objects weight..

Basic principles
Some of the basic pursuits of physics, which include some of the most prominent developments in modern science in the last millennium, include: Describing the nature, measuring and quantifying of bodies and their motion, dynamics etc.
Energy conservation, conversion, and transfer..

The main reason to study physics is because you are curious about how the world works.
In addition to that knowledge, you gain a set of incredibly useful skills that make you attractive to a wide range of employers.
A physics degree trains you to become an expert problem solver..
we can see that a large proportion of physical equations are extremely simple this is because we have developed these for our understanding of all these units and values.
Many phenomena can be described by relatively simple, and often linear, equations well enough for most practical purposes..
Is physical science the same as physics? Physics is a kind of science.
Even though the real boundaries of a type of science are not known, physics is often regarded as the science of the way things move or simply put; the science of energy.
Physics deals mostly with the physical universe without including:
Physics Questions As light from a star spreads out and weakens, do gaps form between the photons.
Can a fire have a shadow.
Can air make shadows.
Can gold be created from other elements.
Can light bend around corners.
Can momentum be hidden to human eyes like how kinetic energy can be hidden as heat? .
yeah , magnetism is definetlely the hardest topic, but when it comes to the exam its more rearranging equations for me.
I think Physics can be specifically hard if you don't breakdown the topic and if you don't use the specification, which is why flashcards are an amazing form of revision.
Particulary from Brainscape .
Physics is difficult for most people to grasp because many of the facts of physics are un-intuitive.
As Peter March explains in his answer, human brains are good at understanding and estimating motion of “normally-sized” bodies at “normal” speeds.
