Ch 22: ORELA General Science: Physics of Motion

About This Chapter

Revisit the concepts of speed, velocity and acceleration by watching fun videos and taking quick quizzes. You'll easily be prepared to answer related questions on the ORELA General Science exam after you watch the lessons in this chapter.

ORELA General Science: Physics of Motion - Chapter Summary

For a fresh look at the physics of motion before the ORELA General Science exam, watch our fast and flexible videos. Each lesson breaks out a larger concept into bite-sized chunks covering:

  • Formulas for speed and velocity
  • Acceleration equation
  • Distance and displacement in physics
  • How displacement of an object is determined
  • Equation used in linear momentum
  • Theorem for momentum and impulse
  • Formula for conservation of linear momentum
  • Differences between scalars and vectors

Convenience is key in these lessons, which can be viewed whenever your schedule allows and from any location using your mobile device. Videos take about 5-10 minutes to watch but provide all the info you need to know about the topic in an entertaining format that makes your review for the exam fun and simple.

ORELA General Science: Physics of Motion - Chapter Objectives

The ORELA General Science exam measures your grasp of general science principles in four areas. It is a requirement to earn a license as a general science teacher in Oregon and is composed entirely of multiple-choice questions. Physics of motion knowledge is tested in the physical science domain, which makes up 37% of the exam. If you want to get comfortable with the style of the questions you'll find on this computer-based exam, take the quizzes that come with our lessons and use the same format as the exam questions.

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.

Acceleration: Definition, Equation and Examples

2. Acceleration: Definition, Equation and Examples

Acceleration can be a tricky topic for many students who tend to get hung up on an object's speed. In this lesson, we will explore the common aspects of acceleration and why speed is not always important.

Distance and Displacement in Physics: Definition and Examples

3. Distance and Displacement in Physics: Definition and Examples

Distance and displacement might seem like similar terms but in physics, understanding the difference can mean getting a question right instead of wrong. In this lesson, we will define these terms and illustrate how easy it is to confuse the two.

Velocity vs. Time: Determining Displacement of an Object

4. Velocity vs. Time: Determining Displacement of an Object

There is a lot of information you can determine by looking at a velocity vs. time graph. In this lesson, we will use a little geometry to calculate the displacement of the object represented by the graph.

Linear Momentum: Definition, Equation, and Examples

5. Linear Momentum: Definition, Equation, and Examples

Any moving object has momentum, but how much momentum it has depends on its mass and velocity. In this lesson, you'll identify linear momentum, as well as see examples of how an object's momentum is affected by mass and velocity.

Momentum and Impulse: Definition, Theorem and Examples

6. 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.

Conservation of Linear Momentum: Formula and Examples

7. Conservation of Linear Momentum: Formula and Examples

The law of conservation of momentum tells us that the amount of momentum for a system doesn't change. In this lesson, we'll explore how that can be true even when the momenta of the individual components does change.

Scalars and Vectors: Definition and Difference

8. Scalars and Vectors: Definition and Difference

In this lesson, we will examine scalars and vectors, learn why it is important to know the difference between the two and why remembering to add a direction to many of your exam answers could be the reason you get it right or wrong.
