What to Expect from Study.com Physics 112 Class 📖

If you are taking Physics 112: Physics II at study.com, prepare yourself to be immersed in a tornado of interesting ideas that govern the functioning of the world—figuratively and literally! The mathematical content of the course begins with simple concepts of heat transfer and ends with electromagnetism and quantum mechanics. If you have ever wondered how light behaves, what makes electricity flow, or how magnetism really works, then this should be your class. Do not worry and it’s simple here, we want to keep it that way. 

Other examples of what you will study include thermodynamics which is a branch of science that deals with heat, energy as well as the relationship between the two. To my surprise, this idea is fairly frequently presented in the exam – pay attention to heat transfer equations and phase transformations! Electric circuits are also always considered a very BIG topic. You’ll understand the flow of electricity through resistors, capacitors, etc which may sound very technical and hard but is quite easy once explained. Understanding electromagnetic fields, and how they relate to current will also be essential—again, something you will have to do quite frequently in your field—the right-hand rule diagrams should also come in handy here. 

Long before reaching the culmination and climax of learning, how humans work, by the end of this course, even he or she would be acquainted with the driver of the current age physics, including quantum mechanics and nuclear physics. Many of these topics are not very obvious but are very essential. Well, these may sound rather complicated now, however, I personally did not experience such difficulties and after continuously building up your background knowledge, the course makes it seem easy once you get there. In addition, it should be noted that mastering all of them will definitely help become a champion in the exam.

Critical Equations and Theories to Keep in Mind 🔑

It’s high time to look into some of the leading issues of study.com Physics 112: Physics II. These are the areas that will be most probably included in the questions that you’re going to be given so let’s take the time to review them. I shall make use of comparison, practical examples, and illustrations whereby I will draw pictures on the board depending on the content of the class.

  1. Ohm’s Law vs. Kirchhoff’s Laws: Understanding Circuits

Concept

Ohm’s Law

Kirchhoff’s Laws

Definition

Describes the relationship between voltage (V), current (I), and resistance (R) in a simple circuit: V = IR.

Governs the conservation of charge and energy in more complex circuits (loops and junctions).

Best for

Simple circuits with one resistor.

Circuits with multiple loops or junctions.

Equation

V = IR

Kirchhoff’s Voltage Law (KVL): ΣV = 0
Kirchhoff’s Current Law (KCL): ΣI(in) = ΣI(out)

Real-life Example

A single lightbulb is connected to a battery.

Wiring in a home or complex electrical systems.

Real World Tip: I would want you to look at Ohm’s Law as a sort of shortcut to be able to immediately determine what is going on in a simple circuit such as a battery powering a bulb. Kirchhoff’s Laws are the “laws of the road” of current and voltage in more complicated circuits, for example, the wiring of an apartment that has several outlets and appliances connected to it.

  1. Time Dilation vs. Space Contraction: Einstein’s Relativity

Concept

Time Dilation

Space Contraction

Definition

Time slows down for objects moving at high speeds.

The length of objects moving at high speeds contracts in the direction of motion.

Equation

T = T₀ / √(1 – v²/c²)

L = L₀ * √(1 – v²/c²)

Example

Astronauts traveling close to the speed of light would age slower than people on Earth.

A spaceship would appear shorter to a stationary observer if it’s traveling close to the speed of light.

Key Idea

Time moves slower the faster you go.

Objects moving fast appear to shrink.

Quick Note: Both these concepts are incorporated into Einsteins special theory of relativity Thus both these concepts are incorporated into Einstein’s special theory of relativity. Particularly imagine if you were to travel at this speed: when you are near light, then it’s just a little crazy with the way they perceive time and space alike. Although it might slightly sound like science fiction, do not worry because you will not experience these effects if you are not planning on traveling in a spaceship soon!

  • First Law of Thermodynamics vs. Second Law of Thermodynamics

Concept

First Law of Thermodynamics

Second Law of Thermodynamics

Definition

Energy cannot be created or destroyed, only transferred.

Entropy (disorder) in a system always increases over time.

Equation

ΔU = Q – W (Change in internal energy = heat added – work done)

ΔS ≥ 0 (Entropy always increases or stays the same)

Real-life Example

A pot of boiling water: energy is transferred as heat, but no energy is lost.

A messy room always gets messier unless you actively clean it (entropy in action!).

Practical Application: The First Law is all about energy balance, like when your phone charges, energy flows in but doesn’t just disappear. The Second Law tells us why things naturally move towards disorder—like why ice melts and hot coffee cools down if you leave them.

  • Wave-Particle Duality: Light Acting Like a Wave and a Particle

Aspect

Wave Nature

Particle Nature

Key Idea

Light exhibits wave behaviors like diffraction and interference.

Light also acts like particles (photons), as proven by the photoelectric effect.

Experiment

Young’s Double-Slit Experiment: shows light creating interference patterns like waves.

Photoelectric Effect: shows light knocking electrons off metal, behaving like particles.

Real-life Example

When light passes through a small slit, it spreads out like a wave.

Solar panels use the photoelectric effect to convert light into electricity.

Remember: It won’t even ally with anyone! I tell you, light is both a wave and a particle! The basic knowledge of wave-particle duality is pivotal to Advanced Physics and this is why solar panels operate as they do.

These are the major areas of study that make the framework of certain courses. : Physics 112: Physics II and you are likely to hear of them when you prepare for your exam. Bear these comparisons and examples in mind – it will make future reviews of basic concepts much easier!

Study.com Physics 112 FAQ❓

Q1: What are the most essential questions that are required to be covered in order to prepare for the exam?

You should pay attention to Ohm’s Law, Kirchhoff’s Laws, the Special Theory of Relativity by Einstein, as well as the First and Second Laws of Thermodynamics. These are rather challenging notions that are explored in Physics 112 in great detail.

Q2: What are the key things to note about AC and DC circuits?

DC circuits have current flow in one direction only while AC circuits change their flow of current periodically. AC is applicable to the transmission of electricity over large distances such as in domestic wiring.

Q3: How can I approach problems involving complicated circuitry?

Circuit analysis should be done by breaking the complex circuits down into simpler parts using Kirchhoff’s Current and Voltage Laws. Then it is required to use Ohm’s Law to solve for different unknowns in a step-by-step manner.

Q4: Do the students really have any need to supplement them with extra notes through memorization of formulas enough for the exam?

It is not useful to cram the formulas though it is useful to know when and how they have to be implemented. There is nothing quite like solving a problem in order to refresh the concepts that one may think they already know.

Q5: How does relativity affect things I see in everyday life?

Relativity affects technologies like GPS, which adjusts for time dilation. It’s not noticeable in daily activities but essential in high-speed applications.
