Objectives of the FTCE Physics: Mechanics Chapter
The state of Florida administers the FTCE Physics exam to test potential teachers' preparedness for physics teaching certification. The subjects covered in this Mechanics chapter comprise about 27% of the approximately 90-question exam. The quizzes alongside each lesson can help you determine how well you've assimilated the material and expose you to the kinds of questions the FTCE Physics exam poses.
Among the physics FTCE's exclusively multiple-choice questions are those that involve the examination of a graph, chart, or number line; those that require an answer to a direct question; and those that call for the completion of a provided sentence. Other questions are asked in response to the outline of a situation or case study.
1. Graphing Basic Functions
Graphs are just like maps - when you know the language! Review how locations have x and y coordinates similar to latitude and longitude, and how to plot points in the Cartesian plane.
2. Slopes and Tangents on a Graph
Hit the slopes and learn how the steepness of a line is calculated. Calculate the slopes between points and draw the tangents of curves on graphs in this lesson.
3. Speed and Velocity: Concepts and Formulas
Did you know that an object's speed and velocity may not be the same? This lesson describes the concepts of speed and velocity relating to objects in motion. We'll look at a specific example to help learn how to calculate both speed and velocity.
4. What is Acceleration? - Definition and Formula
This lesson describes the difference between speed, velocity and acceleration. Examples are used to help you understand the concept of acceleration and learn to calculate acceleration with a mathematical formula.
5. Implications of Mechanics on Objects
Forces act on objects causing them to move. Mechanics is the field of science designated to the study of moving objects. This lesson describes how forces act on objects resulting in motion. Examples are used to describe how forces interact resulting in both simple and complex movement.
6. Newton's First Law of Motion: Examples of the Effect of Force on Motion
This lesson describes Newton's first law of motion, also known as the law of inertia. The interaction between force and motion is explained. Several examples are used to discuss the implications of this law on earth and in space.
7. Newton's Second Law of Motion: The Relationship Between Force and Acceleration
This lesson defines Newton's second law of motion. Examples are used to illustrate how unbalanced forces cause objects to accelerate. The examples are used to practice calculating acceleration and force for objects in motion.
8. Newton's Third Law of Motion: Examples of the Relationship Between Two Forces
This lesson describes Newton's third law of motion. Examples are provided to illustrate how interacting objects experience forces. The lesson explains how objects accelerate as a result of force. Applications of Newton's third law are illustrated in nature, machines, and space.
9. Newton's Laws and Weight, Mass & Gravity
Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.
10. Momentum and Impulse: Definition, Theorem and Examples
To understand how a change in momentum affects an object, we look to impulse. In this lesson, you'll understand how impulse describes an object's change in momentum, as well as how changing the force or time of the impulse can have very different outcomes.
11. Conservation of Mechanical Energy
Energy comes in many forms and for any system can never be created or destroyed. This holds true for mechanical energy, which also obeys this law of conservation of energy. In this video lesson, you'll explore how mechanical energy is converted or transferred between forms and objects.
12. Buoyancy: Calculating Force and Density with Archimedes' Principle
Knowledge of the buoyant force is important when trying to understand why some objects float while other objects sink. In this lesson you'll learn about this unique force and how we apply it to various situations using Archimedes' Principle.
13. Bernoulli's Principle: Definition and Examples
Understanding how a moving fluid's speed and pressure change as it flows along is not only important for building airplanes but also for backyard fun. In this video lesson you'll learn about Bernoulli's principle and identify some practical applications of this concept.
14. 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.
