In each video, instructors convey salient information with a succinct, straightforward lecture. Lesson introductions and summaries offer overviews of the information, and topic-related time markers allow you to jump or return to topics you want to spend additional time reviewing.
Objectives of the FTCE Physics: Modern Physics Chapter
The FTCE Physics test is designed to evaluate candidates' preparedness to be certified physics teachers in Florida. Questions related to modern physics make up around 10% of the total test. Self-assessment quizzes are incorporated into the Modern Physics chapter's lessons; these allow you to assess your own progress in comprehending the material, as well as introduce you to the style of questions you'll find on the FTCE.
Composed of around 90 questions, the physics FTCE is completely multiple-choice. Some questions mandate the interpretation of data from a number line or chart, while others call for the selection of the best words to complete a sentence. Direct questions asking for the correct answer from the provided options are also included, as are case-study scenarios that ask you to indicate your recommended diagnosis or course of action.
1. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan
Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.
2. The Bohr Model and Atomic Spectra
Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.
3. General and Special Relativity: Theory and Examples
Special relativity accounts for the constant speed of light in the absence of surrounding mass. General relativity utilizes the concept of space-time to explain the effect of gravity on the speed of light. This lesson compares special and general relativity and provides examples of how the speed of light is affected by gravity.
4. Mass and Energy: Description and Interchangeable Relationship
Einstein used E = mc^2 to prove that mass and energy are relative to each other. This lesson describes how energy can be converted into mass and mass into energy. Experimental results from particle accelerators are used to demonstrate the relative nature of mass and energy.
5. Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction
When a radioactive particle gives off radiation, what happens to the particle? This lesson will explain the three major types of radiation and what effect they have on the decaying atom.
6. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs
What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.
7. Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy
When you hear the term 'nuclear power,' what comes to mind? Do you know where that energy and power is coming from? In this lesson, we are going to zoom in on the nucleus of a helium atom to explain how something as small as a nucleus can produce an extremely large amount of energy.
8. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry
What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.
