Objectives of the TExMaT Master Science Teacher 8-12: Analyzing Forces Chapter
The paper-based TExMaT Master Science Teacher 8-12 certification examination has 90 multiple-choice questions and a case study assignment. The exam is designed to measure your aptitude for teaching science to teenagers and focuses on the following six areas: scientific nature, history and safety (18%); life science (18%); space and planetary science (18%); physical science (18%); instruction, alignment and evaluation (14%); and leadership, mentoring and the teaching and learning environment (14%).
This chapter covers force analysis concepts and you'll answer related questions on the physical science portion of the assessment. Review the ideas by watching convenient, appealing videos and use the lesson quizzes to practice and get a glimpse of the TExMaT format.
1. Force: Definition and Types
Force is everywhere and it comes in a variety of sizes, directions, and types. In this video lesson, you'll identify force as well the different types of force that objects may experience.
2. Forces: Balanced and Unbalanced
Forces are needed to start or stop an object's motion, but can also be involved when an object is at rest or already traveling at constant velocity. In this video lesson, you'll identify the difference between balanced and unbalanced forces, understanding how they affect the movement of objects.
3. Net Force: Definition and Calculations
Because forces are vectors, we can't simply add them up to get a total amount of force on an object. Instead, we calculate the net force, which is important to understand because it tells us about an object's state of motion.
4. Determining the Individual Forces Acting Upon an Object
Objects constantly have forces acting on them whether they are moving or at rest. In this video lesson, you'll understand how to identify the individual forces acting on an object by reviewing the different types of forces and the use of free-body diagrams.
5. Identifying Action and Reaction Force Pairs
Good things often come in pairs, and forces are no exception. In this lesson you'll explore Newton's second and third laws of motion to understand how action and reaction pairs affect objects interacting with each other.
6. Free-Body Diagrams
Forces that act on an object can be drawn through special vector diagrams called free-body diagrams. In this video lesson you'll identify how to correctly represent forces in a free-body diagram through vector arrows and force labels.
7. What Are Simple Machines? - Definition, Types & Examples
If you need to move or lift a heavy object, it would be wise to use a simple machine. Though these devices are far from fancy or high-tech, they are extremely helpful for getting work done.
8. Inclined Planes in Physics: Definition, Facts, and Examples
If an object is not horizontal to the ground, it may be on an inclined plane. We need to adjust both the calculations and the free-body diagram when determining the net force on an object on an inclined plane. Learn how in this lesson.
9. The Normal Force: Definition and Examples
The normal force is also called the contact force because it only exists when objects are touching. In this lesson, we will investigate what the normal force is and how to calculate it on flat and inclined surfaces.
