Channel Title: Spahn's Science Lectures Channel Description: Mr. Spahn was born and raised in South Milwaukee, WI before moving to Florida for an undergraduate education at Florida Tech. In 2013, he received his B.S. degree with a double major in astrophysics and mathematical sciences. Mr. Spahn then moved to Texas to pursue a masters degree in physics at Texas A&M University-Commerce, which he obtained in 2015. During this time, he also served as a teaching assistant, a research assistant, stockroom manager, and was the president of the Society of Physics Students chapter. In 2014, he was awarded an NSF STEM scholarship for his research of a cataclysmic variable star system and an AAPT outstanding physics teaching assistant award for his contributions in the classroom. Mr. Spahn joined the faculty at Southeastern Oklahoma State University in 2015 and now teaches courses in Physics 1, Physics 2, Astronomy, Earth Science, concepts in physics, and Physical Science, and has earned back-to-back excellence in teaching awards in both 2020 and 2021. <video> College Physics 1: Lecture 29 - Forms of Energy Description: In this lecture, we discuss the four main forms of energy that we will use and introduce an equation for each. 0:00 Kinetic Energy 7:23 Example 1 13:44 Gravitational Potential Energy 18:36 Example 2 21:20 Elastic Potential Energy 27:19 Example 3 29:45 Thermal Energy 35:10 End of Lecture Questions </video> <video> College Physics 1: Lecture 26 - Impulse and Momentum Description: In this lecture, we introduce impulse and momentum as we begin our analysis of the interaction between objects during a collision. 0:00 Impulse 8:13 Example 1 13:10 Momentum 19:02 Impulse-Momentum Theorem 24:09 Example 2 28:50 End of Lecture Questions </video> <video> College Physics 1: Lecture 30 - Conservation of Energy Description: In this lecture, we discuss conservation of energy and solve a couple conservation problems. 0:00 Conservation of Energy 3:21 Problem-Solving Strategy 7:57 Example 1 17:45 Example 2 </video> <video> College Physics 1: Lecture 25 - Moment of Inertia and Rotational Dynamics Description: In this lecture, we introduce moment of inertia and then bring all of our rotation topics together to solve rotational dynamics problems. Angular velocity, angular acceleration, torque, center of gravity, moment of inertia, etc. all combine to make our lives a little difficult. 0:00 Moment of Inertia 9:24 Example 1 18:35 Moment of Inertia for Common Shapes 21:25 Rotational Dynamics 24:37 Example 2 33:55 Example 3 43:22 End of Lecture Question </video> <video> College Physics 1: Lecture 28 - Work and Energy Description: In this lecture, we introduce work and energy with a discussion of the different types of energies and how they may be transformed and/or transferred. This sets the foundation for us to bring it all together with conservation of energy in upcoming discussion(s). 0:00 Forms of Energy 7:06 Energy Transformation 10:23 Energy Transfer 12:36 Work-Energy Equation 14:33 Work 23:24 Example 1 27:23 End of Lecture Questions </video> <video> January 4: Perihelion Day - The Day We are Closest to the Sun! Description: Today (January 4th) we are at perihelion, which means that we are the closest to the Sun that we get in orbit! But it is winter (in the northern hemisphere), so shouldn't it be warmer if we are closer to the Sun? Let's discuss... </video> <video> Channel Update: Lightboard and More! Description: Over my winter break, I spent a lot of my time building a lightboard and setting up my home office for the primary purpose of creating videos both for my students and for this channel. This video begins with a tour of the new setup before showing you a sample of what it can do. This is all very new, and I still have some kinks to work out, but I am very excited to enter this new stage in content creation for the channel! Hoping to release better content, and to do so more consistently from this point forward. My next few videos will be the final missing lectures in my Physics 2 playlist, solely use my old method of lecture recording. From there...who knows! I might begin covering special topics, begin a new series, etc. Time will tell. As always, though, thank you so, so much for being here. Your time, as well as all the wonderful comments I've been getting both mean the world to me. Never stop learning! </video> <video> College Physics 2: Lecture 13 - Resistors, Energy, and Power Description: Note: Old video recording being uploaded now. </video> <video> College Physics 1: Lecture 24 - Torque and Center of Gravity Description: In this lecture, we continue our discussion of rotational motion with the concepts of torque and center of gravity. 0:00 Torque 9:57 Example 1 16:33 Gravitational Torque and Center of Gravity 22:02 Example 2 28:51 End of Lecture Questions </video> <video> College Physics 2: Lecture 8 - Electric Potential and Conservation of Energy Description: In this lecture, we analyze how energy can be used to describe the behavior of charges in electric fields by use of conservation of energy. 0:00 Electric field analogy 3:52 Electric potential vs. potential energy 6:03 Waterfall analogy of electric potential energy 10:26 Conservation of energy 19:17 Example 1 23:37 Example 2 31:28 End of lecture question </video> <video> College Physics 1: Lecture 27 - Conservation of Momentum Description: In this lecture, we introduce an important law of physics - conservation of momentum. This is the first conservation law we deal with, and many problems can be solved via it's application. 0:00 Conservation of Momentum 10:08 Example 1 17:52 Example 2 24:15 Example 3 40:17 End of Lecture Questions </video> <video> College Physics 2: Lecture 7 - Electric Potential and Potential Energy Description: In this lecture, we are presented with a basic introduction to the concepts of electric potential and electric potential energy. We learn how a potential difference (voltage) is created and what creates them. </video> <video> College Physics 2: Lecture 12 - EMF, Resistance, and Ohm's Law Description: Note: Old video recording being uploaded now. </video> <video> College Physics 2: Lecture 9 - Calculating Electric Potential Description: In this lecture, we analyze how to calculate the electric potential both at a point between the plates of a parallel plate capacitor and at a point in space around a point charge.
