How to translate rotational motion to linear motion (angular to tangential)

How to solve for linear distance, speed, and acceleration when given angular or rotational kinematic quantities. This is often called translational motion because we are translating the rotations of a wheel to the linear distance traveled or similar things.

for the example at min 6 why would we divide the radius by 2 if it states that .28 m is the radius. I thought we only divide if it states it is the diameter.

Hey Chris, you are right. I should have divided by 0.28 m instead of 0.19 m because 28 cm is the radius (not the diameter). Sorry for the error!

Hello How To Physics! I do not know you personally, as I am not one of your students, but I wanted to thank you. I took my AP Physics C exam during the beginnings of May and I got my scores this morning. Shockingly for me, I passed with a 4 and I came straight to your channel's comment section because I felt that it would be right to show my appreciation for the help and guidance through the whole studying process that I had right before the exam. It was stressful to find the right review material online until I came upon this channel, so again, thank you for the videos and thank you for the engaging lessons that made me love this subject so much. Next up for me is AP E&M ! Good luck and enjoy the rest of your summer.

That is so AWESOME! Seriously, congratulations. Glad these dumb little videos could help you out!

Linda Taylor sent my the link to your channel!!! Can’t wait to pass my phys 172 exam 😭😭😭😭😭 thank you bae

Hello, why does the law, linear quantity = angular quantity x r not apply for toruqe as then it would be F=TorquexR when it is really Torque=ForcexR? Thank you

thank you how you physics
