What to Expect from Study.com Science 102 Class📖
Ok, so let me list out what you should expect in study.com Science 102: Principles of Physical Science. You may remember the old saying, “This is where it all starts,” well this concept is the starting point for understanding physics and chemistry which are the two sciences that explain how things work. You’re going to be going over some basic fundamental concepts that you might find hard at the moment but they make everything that follows in science so much easier as you progress.
First, let’s embrace thermodynamics Moving on, the next law is the second law Of thermodynamics. Yes, I know, the name alone is very frightening but actually, it’s just about heat and how it behaves. It lies in energy transfer; whether it is in warming the coffee beverage or in fueling one’s car engine. Some of the content areas you will cover include heat transfer, the specific heat capacity, and phase changes that are sure to feature in the exam. Be friends with this topic as questions related to heat, temperature, and energy are a portion of the physical science large questions.
The next topic we are going to learn is electric power and circuits. In this section, you will understand more about how electricity works and how it is utilized in the world of technology including the one you are using to read this; your smartphone, your toaster, etc. New elements like Power and the pioneering knowledge of the relationship between Electromagnetic force, current, voltage, and resistance, which come with Ohm’s Law will be a great guide when solely asked to calculate power or when solving circuit diagrams. Before it’s possible to analyze the types of circuit connections, it is also important to memorize the basics of series and parallel circuits which will assist in answering numerous questions on the exam.
Next, you will go to the area of magnetism and electromagnetic motors. Sounds fun, right? This part of the course consists of how magnetic fields function and the use of magnetic fields – How a compass works and why fridge magnets stick on the refrigerator. This is the kind of topic that you can easily think of as being rather theoretical at first glance, but believe me, it is actually very much down to earth once you learn how electricity and magnetism interact in everyday use.
Finally, let us briefly describe the general chemical reactions and equilibrium that you are going to receive in the process. This section simply explains how agents combine, chemically react, and create new forms of compounds as well as how they balance out. All the reactions involving the change of an acid and a base into water and salt will be common in the tests; thus understanding how acids and bases react, how to balance chemical equations, and what is meant by equilibrium will be of great benefit.
In a nutshell, this class goes below the surface exploring the basic laws that govern the physical existence of things. No problem; just let me know when you would like me to begin studying; I will post a plan that will first divide all the information into categories so as not to overwhelm you. These four core concepts: thermodynamics, electric circuits, magnetism, and chemical reactions are the concepts that are very essential for you in your exams so we will make preparations in readiness for the tests!

Must-Know Laws and Theories to Focus On 🔑
In this section, we’re breaking down the key concepts from Study.com Science 102: Principles of Physical Science that you absolutely need to master. These topics are fundamental and will likely show up in your exam. Let’s go over some of the most important ideas and make them easier to digest, with some comparison charts and real-life examples to help you understand better!
- Transverse vs. Longitudinal Waves
It is important to distinguish between these two types of waves in the case of all the chapters dealing with sound and light waves. Here’s a quick comparison to help you out:
Feature | Transverse Waves | Longitudinal Waves |
|---|---|---|
Particle Movement | Perpendicular to the direction of the wave | Parallel to the direction of the wave |
Examples | Light waves, radio waves | Sound waves, seismic P-waves |
Medium Required? | Can travel through a vacuum | Requires a medium (solid, liquid, or gas) |
Characteristics | Peaks (crests) and valleys (troughs) | Compressions and rarefactions |
Real-life Example: Imagine a wave that moves up and down or a wave that makes a stone drop in water ripple – that is a transverse wave. One can now try to picture a rubber band being stretched and then released – that is a longitudinal wave!
- Newton’s Laws of Motion
These are basic laws of physics that determine the interaction between an object and the force that is applied to the object. Here’s a summary of the three laws:
Newton’s Law | Description | Example |
|---|---|---|
First Law (Inertia) | An object in motion stays in motion, and an object at rest stays at rest. | A book stays still on a table until you push it. |
Second Law (F=ma) | Force equals mass times acceleration. | Pushing a heavy box requires more force than a light one. |
Third Law (Action-Reaction) | For every action, there’s an equal and opposite reaction. | When you jump off a boat, it moves backward. |
Real-life Example: For example when you are skating and decide to stop, you will continue to move forward simply because of this law! That was Newton’s First Law in action if you were asking!
- Chemical Reactions: Endothermic vs. Exothermic
Different chemical reactions can either give out energy or require energy to be supplied and this is important to note.
Reaction Type | Energy Transfer | Real-life Example |
|---|---|---|
Endothermic | Absorbs energy (feels cold) | Photosynthesis in plants |
Exothermic | Releases energy (feels hot) | Combustion in engines (burning fuel) |
Remember: In exothermic reactions energy is released to the surroundings and that is why when one touches fire it feels hot whereas in endothermic reactions the energy is absorbed by the reactants from the surroundings so when one touches an ice pack they feel cold.
- Ohm’s Law in Circuits
The rules of circuit analysis start with Ohm’s Law. It defines voltage, current, and resistance where voltage is represented by V, current is represented by I and resistance is represented by R.
Formula | V = I × R |
|---|---|
Voltage (V) | The potential difference or push that drives the current. |
Current (I) | The flow of electric charge. |
Resistance (R) | The opposition to the flow of charge. |
Real-life Example: If you switch on a lighted bulb, then you will see that the electricity flows in the circuit but if there is high resistance such as a bad wire, the bulb will not be able to light up completely!
Conclusion:
These are the central topics that need to be well studied in order to succeed in the course of Study. California State University, Bakersfield Course: com Science 102: Principles of Physical Science. Use the tables, real-life examples, and comparisons to get a clearer understanding, and remember: The more you link these ideas to real-life scenarios, the better you are going to remember them!
