Elevator Physics Problem - Normal Force on a Scale & Apparent Weight

preview_player
Показать описание
This physics video tutorial explains how to find the normal force on a scale in a typical elevator problem. It discusses how to calculate the apparent weight of a person when the elevator is at rest, moving upward with constant speed, downward with constant velocity, accelerating upward or downward. It uses free body diagrams and net force calculations to find the apparent weight shown on a scale which is equivalent to the normal force of the scale on the person.

That explanation of that "feeling" of acceleration deserves an academy award for best screen writing. That. Was. Epic.

If I somehow manage to make it into radiology, if I ever make it to becoming not just a technician, but a full on licensed radiologist, it will be thanks to you and your videos. I hope I'll remember to try to get in contact with you, so that if you or your family ever need such services, I will give them at no charge to you or your family. You are truly a blessing.

Your free fall in an elevator explanation is the very best one I have found on youtube. Congrats.

Oh my gosh, that part about the free fall and feeling like you’re in space, and that you feel lighter or heavier based on how the elevator is moving, that’s so dope! I actually got excited watching this. Maybe I’ll actually end up liking physics.

Thank you so much. I missed the unit where we covered this and other motion problems in class and had to prepare for the test by myself. Your videos really helped me.

I can't explain how relieved I feel when I find your videos. Your voice is so comforting, it feels like a hug saying it's gonna be alright. Reassuring. This was such an rare topic, I doubted you'd have a video on it. Your library is HUUUGGEEE

Hands down the best video explaining the acceleration in the elevator! Able to understand it just by watching it once!

Crash course in physics because I missed the first month of classes. This video taught me what the 2 hours recorded class was showing. Thank you!

Sir this video was able to teach me a concept in 12 minutes which none of my teachers could teach me in 3 weeks!!
