Ch 2: Biomechanical Principles

About This Chapter

The subject of this chapter is biomechanical principles. Our experts developed these lessons for you to get to know about kinematics, the laws of inertia, unbalanced forces, and various types of motion.

Biomechanical Principles - Chapter Summary

Take a look at biomechanical principles as they're presented in the lessons of this chapter. See what biomechanics applications exist in our everyday lives, calculate relative velocities in basic situations, examine Newton's first law, and learn about different states of stability.

Get familiar with the meaning and applications of biomechanics, and compare the relationship between motor skills and movement patterns to the principles of biomechanics and kinesiology. Explore additional lesson information, such as:

  • A graphical representation of kinematics
  • Linear, circular, simple harmonic and projectile types of motion
  • Explanation and equations of rotational kinematics
  • Kinematics and relative velocity
  • Newton's law of inertia
  • Center of gravity and its relation to stability
  • Balanced versus unbalanced forces
  • Safe and efficient exercise through the use of biomechanics

Lessons are designed to take five to ten minutes to complete. Animated and fun to watch, the video lessons engage viewers with bright graphics and narration. The lesson transcripts highlight important terminology, and they can be printed out, as can your quiz results.

What is Biomechanics? - Definition & Applications

1. What is Biomechanics? - Definition & Applications

Exactly what is the study of biomechanics? In this lesson we'll define the field and explore just a few of the applications biomechanics has in our everyday lives.

Kinematics: Definition & Graphical Representation

2. Kinematics: Definition & Graphical Representation

After completing this lesson, you will be able to explain what kinematics is, and how graphical representations are used in kinematics. A short quiz will follow.

Motion: Linear, Simple Harmonic, Circular & Projectile

3. Motion: Linear, Simple Harmonic, Circular & Projectile

While you may be able to define 'motion' as it relates to science, do you know how simple harmonic, circular, linear and projectile motion differ from one another? Continue reading to find out more about these different types of motion, and then see if you can answer the questions on the follow-up quiz.

Rotational Kinematics: Definition & Equations

4. Rotational Kinematics: Definition & Equations

After watching this lesson, you should be able to explain what kinematics is, give a rotational variable that corresponds to each linear kinematic variable, and solve problems using rotational kinematics equations. A short quiz will follow.

Understanding Relative Velocity in Kinematics

5. Understanding Relative Velocity in Kinematics

After completing this lesson, you will be able to explain what relative velocity is in kinematics and calculate relative velocities in basic situations. A short quiz will follow the lesson summary.

Laws of Inertia: Definition & Formula

6. Laws of Inertia: Definition & Formula

Inertia is the tendency of an object to stay at rest or in motion. Learn more about Newton's first law as it explains how forces acting on an object are related to the object's mass and motion through several examples, and test your knowledge with quiz questions.

Stability & Center of Gravity

7. Stability & Center of Gravity

Discover what stability means and why center of gravity is so important to understanding it. Then learn about the different states of stability and how to tell the difference between them.

Forces: Balanced and Unbalanced

8. Forces: Balanced and Unbalanced

Forces are needed to start or stop an object's motion, but can also be involved when an object is at rest or already traveling at constant velocity. In this video lesson, you'll identify the difference between balanced and unbalanced forces, understanding how they affect the movement of objects.

Principles of Biomechanics & Kinesiology Related to Motor Skills & Movement Patterns

9. Principles of Biomechanics & Kinesiology Related to Motor Skills & Movement Patterns

In this lesson, we review how biomechanics and kinesiology relate to both motor skills and movement patterns. We also discuss some of the basic principles of each and how they relate to human movement, the brain, muscles, and the body.

Using Biomechanics for Safe & Efficient Exercise

10. Using Biomechanics for Safe & Efficient Exercise

In this lesson you explore ways to use biomechanics for safe and efficient exercise. You define biomechanics and you learn how they apply to some of the most popular sports in the world. You also learn about types of muscles and muscle movements.
