Calculating Angular Momentum Straight Line Motion | AP Physics 1 - Unit 6 Lesson 5

Can an object moving in a straight line really have angular momentum?

Yes — and this concept confuses a huge number of AP Physics 1 students.

In this lesson, we break down how to calculate angular momentum for straight-line motion.

✅ What You’ll Learn in This Video:

Why straight-line motion can still have angular momentum
How angular momentum depends on the axis of rotation
When angular momentum is zero — and why
How to use MVR correctly (and when it works)
Perpendicular vs parallel components (critical exam skill)
How to assign direction and sign to angular momentum
Multiple AP-style examples step-by-step
