About This Chapter
Who's it for?
This unit of our AP Physics 1 Homeschool course will benefit any student who is trying to learn about motion and gravitation. There is no faster or easier way to learn about motion. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about centripetal force, uniform circular motion and Newton's law of universal gravitation.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a physics curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a motion unit exam confirm understanding or identify any topics that require review.
Motion Unit Objectives:
- Understand the mathematics behind uniform circular motion.
- Learn what centripetal force is and how it is calculated.
- Examine Newton's law of universal gravitation and its applications.
- Explore gravitational attraction by an extended body.
- Discover the components and results of Cavendish's gravity experiment.
1. Cavendish's Gravity Experiment & the Value of G
After watching this lesson, you will be able to explain what the gravitational constant is and explain how the Cavendish Experiment can be used to figure out the value of big-G. A short quiz will follow.
2. Centripetal Force: Definition, Examples & Problems
After watching this video, you should be able to explain what centripetal force is, identify the centripetal force in a particular situation, and solve problems using the centripetal force equation. A short quiz will follow.
3. Gravitational Attraction of Extended Bodies
After watching this lesson, you will be able to explain what an extended body is, understand the derivation for the force of gravity between a point charge and a long, thin bar and solve problems using the result of that derivation.
4. Newton's Law of Gravitation: Definition & Examples
This lesson explains how gravity works mathematically and teaches you how to use Newton's Law of Gravitation to solve problems. A short quiz will follow.
5. 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.
6. 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.
7. What is Acceleration? - Definition and Formula
This lesson describes the difference between speed, velocity and acceleration. Examples are used to help you understand the concept of acceleration and learn to calculate acceleration with a mathematical formula.
