Ch 2: Vectors in Physics: Help and Review

About This Chapter

The Vectors in Physics chapter of this High School Physics: Help and Review course is the simplest way to master vectors in physics. 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 vectors.

Who's It For?

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

  • Students who have fallen behind in understanding vectors
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning physics (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about vectors
  • Students who struggle to understand their teachers
  • Students who attend schools without extra physics 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 Vectors in Physics 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 Vectors in Physics chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any vector question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students Will Review:
