Instructional Ideas

• Use as an opener for a lesson on momentum
• After viewing the video, challenge learners to calculate the velocity of colliding vehicles that are heading toward each other

Classroom Considerations

• Review the mathematics of working with formulas to prepare for the lesson
• The 22nd lesson in a 49-part video series

• This video is hosted on YouTube

Pros

• Progression of the examples scaffolds to the most difficult question, making it easier to understand
• The way the narrator explains the formula helps scholars understand the different components

Cons

• None
