Praxis Biology & General Science: Physics Review: Mechanics - Chapter Summary

With our lessons, you can review the physics and mechanics topics covered by the Praxis exam, including Newton's laws and the implications of mechanics theory. Video instructors help you understand all the theories, names, important principles, and scientific terminology to make each lesson easy to remember and apply. Lessons in this chapter include:

  • Speed and Velocity: Concepts and Formulas
  • What is Acceleration? - Definition and Formula
  • Implications of Mechanics on Objects
  • Newton's First Law of Motion: Examples of the Effect of Force on Motion
  • Newton's Second Law of Motion: The Relationship Between Force and Acceleration
  • Newton's Third Law of Motion: Examples of the Relationship Between Two Forces
  • Newton's Laws and Weight, Mass & Gravity

After watching our short, fun videos, be sure to take the brief multiple-choice quizzes to gauge your understanding of the material. Accompanying transcripts enable you to read along with the videos.

Praxis Biology & General Science: Objectives

The Praxis Biology & General Science exam is used to determine your readiness to be licensed as a science or biology teacher in your state. Please note that the exact requirements for teacher licensing - including the minimum score you'll need to be eligible - vary by state. The test looks at your ability to:

  • Understand the connections between science, technology, and applications in society
  • Interpret scientific data collected in the field and observed in the laboratory
  • Apply scientific principles and theories to common scenarios

The Biology & General Science test consists of 120 multiple-choice questions. Physics accounts for about ten percent of the exam, or about 12 questions. The test takes about two hours to complete.

Test your knowledge with a 30-question chapter practice test
Speed and Velocity: Concepts and Formulas

1. 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.

What is Acceleration? - Definition and Formula

2. 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.

Implications of Mechanics on Objects

3. 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.

Newton's First Law of Motion: Examples of the Effect of Force on Motion

4. 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.

Newton's Second Law of Motion: The Relationship Between Force and Acceleration

5. 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.

Newton's Third Law of Motion: Examples of the Relationship Between Two Forces

6. 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.

Newton's Laws and Weight, Mass & Gravity

7. 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.
