# Ch 4: Laws of Motion: Help and Review

The Laws of Motion chapter of this Physics 101: Help and Review course is the simplest way to master force and the laws of motion. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of the laws of motion.

## Who's It For?

Anyone who needs help learning or mastering laws of motion material will benefit from the lessons in this chapter. There is no faster or easier way to learn the laws of motion. Among those who could benefit are:

• Students who have fallen behind in understanding how to perform calculations using Newton's laws of motion
• Students who struggle with learning disabilities or learning differences, including autism and ADHD
• Students who prefer multiple ways of learning science (visual or auditory)
• Students who have missed class time and need to catch up
• Students who need an efficient way to learn about the laws of motion
• Students who struggle to understand their teachers
• Students who attend schools without extra science learning resources

## How It Works

• Find videos in our course that cover what you need to learn or review.
• Press play and watch the video lesson.
• Refer to the video transcripts to reinforce your learning.
• Test your understanding of each lesson with short quizzes.
• Verify you're ready by completing the Laws of Motion chapter exam.

## Why It Works

• Study Efficiently: Skip what you know, review what you don't.
• Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
• Be Ready on Test Day: Use the Laws of Motion chapter exam to be prepared.
• Get Extra Support: Ask our subject-matter experts any laws of motion question. They're here to help!
• Study With Flexibility: Watch videos on any web-ready device.
