There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.

What are basics of physics?
Physics is a study of how the universe behaves. Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the study of nature in an attempt to understand how the universe behaves.

What is physics 101 all about?
This course focuses on basic physics concepts and connections to everyday life. Course topics include Newtonian mechanics, fluids, heat, vibrations, electricity and magnetism, light and sound, quantum phenomenon, nuclear radiation, relativity, and cosmology.
What are the 4 laws of physics?
These four basic forces are known as fundamental because they alone are responsible for all observations of forces in nature. The four fundamental forces are gravity, electromagnetism, weak nuclear force, and strong nuclear force.
How do I start studying physics?
To learn Physics, it’s crucial to have a basic understanding of the sub-subjects under Physics and the order in which you should study them. It’s best to start with subjects like systems of measurement, followed by vectors. The more complex subjects include fluid mechanics and thermodynamics.
Is physics easy or hard?
Students and researchers alike have long understood that physics is challenging. But only now have scientists managed to prove it. It turns out that one of the most common goals in physics—finding an equation that describes how a system changes over time—is defined as “hard” by computer theory.
How can I study physics?
What are the different types of physics?
- Classical Physics.
- Modern Physics.
- Nuclear Physics.
- Atomic Physics.
- Geophysics.
- Biophysics.
- Mechanics.
- Acoustics.
What is mechanics and its types?
Mechanics may be divided into three branches: statics, which deals with forces acting on and in a body at rest; kinematics, which describes the possible motions of a body or system of bodies; and kinetics, which attempts to explain or predict the motion that will occur in a given situation.
What topics are under mechanics in physics?
- Torque and rotational statics.
- Rotational kinematics.
- Rotational dynamics and energy.
- Angular momentum and its conservation.
What are the 2 types of physics?
There are Two Major Branches of Physics that are Modern and Classical Physics. Further physics sub branches are electromagnetism, Mechanics, Thermodynamics, Optics.
What is the easiest topic in physics?
- Vectors.
- Kinematics.
- Force & Laws of motion.
- Rotation.
- Fluid.
- Gravitation.
- SHM.
- Centre of Mass.
Which is strongest force?
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!)
What is the weakest force?
Gravitational force, the weakest of the four forces, has a strength of 10 to the minus 40, relative to electromagnetism. The force of gravity (along with electromagnetism) has a range of infinity – every single atom in the universe is ‘gravitationally aware’ of every other atom.
Why is gravity weak?
According to string theorists’ best ideas, gravity is so weak because, unlike the other forces, it leaks in and out of these extra dimensions. We only get to experience a dribble of the true strength of gravity.
What are the 12 universal laws?
- #1: The Law of Divine Oneness. Everyone and everything is connected in the world we live in.
- #2: The Law of Energy or Vibration.
- #4: The Law of Correspondence.
- #5: The Law of Cause and Effect.
- #6: The Law of Compensation.
- #7: The Law of Attraction.
- #9: The Law of Relativity.
- #10: The Law of Polarity.
What are the types of force?
- Gravitational force.
- Electric force.
- Magnetic force.
- Nuclear force.
- Frictional force.
What type of math is physics?
You don’t have to be a mathematical genius to study physics, but you do need to know the basics, and college physics classes often use calculus and algebra.

What is the hardest subject?
The hardest degree subjects are Chemistry, Medicine, Architecture, Physics, Biomedical Science, Law, Neuroscience, Fine Arts, Electrical Engineering, Chemical Engineering, Economics, Education, Computer Science and Philosophy. Let’s dive right in, and look at why these subjects are the hardest degree subjects.
Is physics harder than math?
Physics might be more challenging because of the theoretical concepts, the mathematical calculations, laboratory experiments and even the need to write lab reports.
Is physics harder than chemistry?
Physics is considered comparatively harder than chemistry and various other disciplines such as psychology, geology, biology, astronomy, computer science, and biochemistry. It is deemed difficult compared to other fields because the variety of abstract concepts and the level of maths in physics is incomparable.
Why is physics so hard?
Why is Physics harder than Math? Answer: Physics demands problem-solving skills that can be developed only with practice. It also involves theoretical concepts, mathematical calculations and laboratory experiments that adds to the challenging concepts.
