About This Chapter
CSET Science: Forces and Motion - Chapter Summary
This chapter's lessons will help you gain a solid grasp of the principles and foundations of forces and motions in preparation for the California Subject Examinations for Teachers (CSET) Science test. You'll examine Newton's Laws of Motion and learn how they relate to weight, mass and gravity. Other lessons cover speed and acceleration and the various forces that act on a body. The topics in the video lessons include:
- Newton's First Law of Motion: examples of the effect of force on motion
- Newton's Second Law of Motion: relationship between force and acceleration
- Newton's Third Law of Motion: examples of the relationship between two forces
- Newton's laws and weight, mass and gravity
- Pressure and how it relates to fluid flow and buoyancy
- Speed and velocity: concepts and formulas
- Acceleration: definition and formula
- Relationships among position, distance, displacement, speed, velocity and time and simple calculations using these variables for linear and circular motion
- The forces that act on a body (e.g. gravity, pressure, tension/compression, normal force, friction) and describe the net force on the body
- Construct and analyze simple vector and graphic representation of motion and forces
- Identify fundamental forces, including gravity, nuclear forces and electromagnetic forces and their roles in nature
- Explanation and calculation of mechanical advantages for levers, pulleys and inclined planes
- Implication of mechanics on objects
The expert instructors will explain the topics in these lessons, making sure you understand each as you prepare for the test. Your knowledge of a variety of topics relating to forces and motions will give you a sound footing for the CSET, and the video lessons make your studies enjoyable.
Objectives of the CSET Science: Forces and Motion Chapter
California requires that applicants for some teaching credentials pass CSET examinations. The questions on forces and motion are part of the General Science: Subtest I. This science subtest contains 58 multiple-choice questions, with 15 related to the topics covered in these forces and motion lessons. The test also requires you to compose a short response to a question on forces and motion. The self-assessment quizzes included with the video lessons will give you an idea of how the CSET questions are formatted and also allow you to check your knowledge.
1. 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.
2. 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.
3. 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.
4. 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.
5. The Law of Universal Gravitation: Definition, Importance & Examples
Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.
6. 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.
7. Understanding Graphs of Motion: Giving Qualitative Descriptions
You can just look at graphs of straight line motion and accurately describe how that object is moving. In this lesson, we will investigate the basic shapes the graphs can take and what conclusions you can draw from these shapes.
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. Pulleys: Basic Mechanics
Like other simple machines, pulleys can help us lift and move heavy loads with less effort. In this video lesson, you'll learn how pulleys do this as well as how this is possible while still obeying the law of conservation of energy.
10. 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.
11. Balanced Forces: Definition & Examples
In this lesson, you will learn what is meant in physics by 'balanced forces', including how that applies to Newton's 1st Law, as well as some examples of balanced forces in real life. A short quiz will follow.
12. Centripetal Force: Definition, Formula & Examples
When an object is traveling in a circular path, centripetal force is what keeps it fixed in that path. Learn more about this force, how it is calculated and examples of its occurrence. A quiz is provided to test your learning.
