Ch 9: Understanding Motion

About This Chapter

If you have an interest in learning much more about motion, this chapter was made for you. In an effort to help you improve your physical science grades or prepare for an exam, these lessons can help you obtain those goals and objectives.

Understanding Motion - Chapter Summary

There's more to motion than just moving from one place to another, and the lessons in this chapter will show you many of the factors involved. You will learn the definitions of speed, velocity and acceleration and explore the formulas used in calculating them. Other lessons cover different types of motion, such as projectile motion and uniform circular motion. After you have finished working through the lessons, you have the chance to take self-assessment quizzes that give you immediate feedback. By the end of the lessons in this chapter, you should have an understanding of how to do the following:

  • Distinguish the difference between speed and velocity
  • Recall the formula for acceleration
  • Explain the mechanics on objects
  • Describe what projectile motion is
  • Use different motion equations
  • Discover the mathematics behind uniform circular motion
  • Describe how to measure the speed of an object
  • Contrast gravity and projectile motion

After completing this lab, you will be able to explain what acceleration is and collect data to determine the acceleration of an object using graphical methods. A short quiz will follow.

Implications of Mechanics on Objects

6. 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.

Uniform Circular Motion: Definition & Mathematics

7. Uniform Circular Motion: Definition & Mathematics

After watching this lesson, you will be able to explain what uniform circular motion is, in terms of both acceleration and forces. You will also be able to use equations for centripetal force and acceleration to solve problems. A short quiz will follow.

Projectile Motion: Definition and Examples

8. Projectile Motion: Definition and Examples

A projectile is any object that is given an initial velocity and then follows a path determined entirely by gravity. In this lesson, we will introduce projectile motion and touch on a few key facts to keep in mind when working through these problems.

Projectile Motion Practice Problems

9. Projectile Motion Practice Problems

After watching this video lesson, you will know how to use the sets of equations that are used to solve projectile motion problems. Learn how to manipulate them to find the answer you need.
