About This Chapter
Analyzing Motion and Forces - Chapter Summary
When studying topics from the scientific field of physics, it's a good idea to specifically ensure that you learn about ways to analyze motion and forces. Included in this chapter are interactive video lessons that will go over the major scientific laws, definitions, concepts and examples related to force and motion in physics.
Watch these lessons to get comprehensive overviews of each of these laws and discover how you can implement them to analyze motion and forces when studying physics yourself. Our lesson instructors will go over each of these topics, so you should have no issue understanding these somewhat complex concepts. You can watch these lessons to learn about topics such as:
- The laws of inertia
- Newton's Second Law of Motion
- Newton's Third Law
- Inclined planes
- The definition and examples of projectile motion
- The definition and examples of periodic motion
- Conservation of momentum
- Conservation of mechanical energy
- Characteristics of fluids
The chapter's practice quizzes and final exam will help you test your understanding of these topics once you complete each of the lessons. Contact the instructors if you need clarification on any of the points above. Your personal Dashboard will permit you to see much you have learned in this chapter.
1. 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.
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: Physics Lab
After watching this lesson and completing the lab, you will be able to explain what Newton's 3rd Law is, and use an equation to show why two forces can be equal and opposite, and still lead to two objects moving in different ways. A short quiz will follow.
4. 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.
5. 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.
6. Periodic Motion: Definition & Examples
After completing this lesson, you should be able to define and provide examples of periodic motion, as well as describe what makes a periodic motion a simple harmonic motion.
7. Conservation of Momentum: Physics Lab
After completing this lab, you will be able to explain what conservation of momentum is and conduct an experiment to demonstrate conservation of momentum. You can also take the short quiz to test your knowledge.
8. Conservation of Mechanical Energy
Energy comes in many forms and for any system can never be created or destroyed. This holds true for mechanical energy, which also obeys this law of conservation of energy. In this video lesson, you'll explore how mechanical energy is converted or transferred between forms and objects.
9. Fluids in Physics: Definition and Characteristics
Fluids really know how to move! As flowing materials, fluids have some unique properties that help us understand and describe them. In this lesson you'll explore what fluids are and how they are defined in the world of physics.
