Short Description: None Provided

Yes, there are mistakes that many people make when it comes to free-fall acceleration problems. I dispel many misconceptions and explain both why people think they are true and why they actually aren't. Oh, and there are some special effects too!

Content Times:

0:14 Review of the Basics of Free-Fall

1:04 1st Misconception - The acceleration on the way up is positive

2:09 2nd Misconception - The initial velocity going upward is zero

2:45 3rd Misconception - A thrown ball will accelerate faster than a dropped ball

4:00 Reminder - Velocity at the top is zero

4:29 4th Misconception - The acceleration at the top is zero
