Physics 11.1 Rigid Body Rotation (1 of 10) Basics

In this video I will explain the translational, rotational, and combined motion of rigid body rotation.

Every video I need to review for my test, this guy has. All contain definitions, examples, and are short and concise.

When I graduate and make some more extra savings, it would be my honor to donate to you and your awesome videos! Please keep it up.

This comes in so handy as a revision for my exam(1st year undergraduate) which is tomorrow and I've been preparing for a month really intesively, however never enough of clarifications of concepts or making them simpler, and who does it better than you! Thank you!

[ahappyimago]

I love you, man. You're the best physics teacher on Youtube :)

[iGottic]

Researching rigid body dynamics for my own personal use, and even as a highschool student you do a great job explaining this :)

Thank You So much !!!!
Best online course teacher

This account is incredibly helpful. You're an awesome teacher compared to my physics prof, thanks for putting up these videos!

[josevelasco]

This video was my thousandth like on YouTube.

[mohammadrezai]

Your lectures help so much, keep up the work prof

Yashash,
Wouldn't the average velocity of each portion of the tire be the velocity of the car?

[nguyenkhoa]

Sir, I have a problem that seems to be pretty simple but I cannot get the right answer. I hope you can take a look and give me some hints about it, I think I have trouble calculating the couple C.

The problem is: "A homogeneous cylinder of mass m and radius R is at rest on a horizontal plane when a couple C is applied clockwise. Determine the magnitude of the coefficient of friction between the wheel and the plane so that rolling will occur."

The answer is: coefficient of friction >= (2C/3)/(mgR)

Your videos are always awesome. You teach us what school is supposed to teach...Thank you very much, sir.

2:45 to 3:10 "tremendous acceleration" Yes sir I 100% agree!
Now what if the rim speed were 1039mph and we had a delta V of 2078mph over a 12hr time frame. And lets say the tire were made of soil. Is the tensile strength of soil strong enough to withstand those tremendous accelerations?

Can you do a vector analysis of the rotating globe while it is "translating" through space around the sun at 66, 000 mph? Would there be a momentary instance where the velocity would be zero like on a rotating tire going down the road? Will we have "tremendous accelerations" and then reduced velocities repeating over and over again just like the spinning wheel "translating" down the road? Will you do it or as one Youtube channel called Kryptonite Physics has pointed out "There is a reason why in Astrophysics they do not use rotating reference frames that are moving is because it all falls apart if they do".

Amazing explanation professor. Thank you for you videos.

Awesome, I'm studying exactly this topic in physics right now.

Hello there,
First. thank you for this video!

You said that the tremendous acceleration of a particle tire when it's at the bottom hitting the road is part of the reason why there is a lot of heating effect taking place by the rotation of the tire.

I have 3 questions about that:
1. How can I calculate the exact amount of heat generated from this acceleration?
2. What are the other reasons causing the tire's heating? How can I calculate them?
3. How much (+/-) of the total heating is caused by this effect (heating caused by acceleration)?

Thank you!

Rigid body rotation and translation prove that people on a globe earth rotating and translating(orbiting the sun) would experience acceleration and deceleration. I don't feel the earth beneath me accelerating or decelerating which disproves the globe model. What do you think Michel?

[raikiri]

What a great great simple explanation :-)Goooo Michel :)

[ismail]

Thank you, but still dont understand bottom of tire not moving, , but it is not stay at same contact point with earth and changed point of contact??. not moving mean not changing place

[jocelyndelangel]

You should write a book!! I wish you were my mentor
