About This Chapter
AP Physics 1: Newton's Second Law of Motion - Chapter Summary
As you prepare for your AP Physics 1 exam, you'll want to make sure you have a thorough understanding of Newton's second law of motion so you can be prepared for these types of questions. The lessons in this chapter go over essential information related to determining the individual forces acting on an object, the implications of mechanics on objects, and much more. Once you complete the lessons in this chapter you should have the knowledge to:
- Explain the relationship between forces and acceleration
- Determine the acceleration of an object
- Discuss the law of action and reaction and give examples
- Detail the relationship between air resistance and an object in free fall
These brief lessons were created by expert instructors and deliver the material in a straightforward and interesting manner. You'll be able to assess your knowledge with the quizzes throughout the chapter, which allows for a quick determination of whether you need to continue to review an objective or to go on to another lesson. This process lets you save time and focus on the most needed areas for review.
1. 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.
2. Determining the Acceleration of an Object
Acceleration is a change in an object's state of motion. A few variables need to be identified to calculate an object's acceleration, but once we have those values, we can put them into a simple equation to find out how quickly or slowly an object's velocity is changing.
3. Action and Reaction Forces: Law & Examples
Action force is force acting in one direction. Reaction force is force acting in the opposite direction. Learn more about Newton's Third Law as it explains action and reaction forces through several examples, and test your knowledge with quiz questions.
4. Determining the Individual Forces Acting Upon an Object
Objects constantly have forces acting on them whether they are moving or at rest. In this video lesson, you'll understand how to identify the individual forces acting on an object by reviewing the different types of forces and the use of free-body diagrams.
5. 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.
6. Air Resistance and Free Fall
Through experiments by Galileo and Newton, we can understand why all objects in free-fall experience the same acceleration, ''g''. We can also see why air resistance affects a falling object's velocity and how this can lead to a falling object reaching a terminal velocity.
