Hey Flippin. I know you get bombarded with thankful comments, but I have been using your videos for the past 3 years now. I found you when I took AP physics 1, and I have came back to your videos through AP Physics C Mechanics, E&M, and now I'm in college rewatching your videos before my physics test. Thanks again for your honest work.

Sorry, another question is, how does the fuction look like in the real problem with x dm or r dm? I did not get the part about dm what it means and stands for

@carultch

2 жыл бұрын

The d means "infinitesimal difference in" the following quantity. The dm refers to an infinitesimal mass element. Concepts like center of mass and moment of inertia are defined through the concept of dm. You examine each particle that comprises the system, and add up (aka integrate) r*dm in the case of center of mass, or r^2*dm in the case of moment of inertia. To make more sense of dm, you usually re-write it in terms of another variable that is easier to adjust and conceive of how to integrate, by coming up with a shape for your infinitesimal mass element. Such as replacing it with rho*A*dx, where A is cross-sectional area, rho is the density, and dx is an infinitesimal change in x. This is how you would use this, in the case of a thin rod.

Good stuff

Does conservation of momentum work when there are more than two objects in the system (ex. a collision between three vehicles)?

@FlippingPhysics

4 жыл бұрын

As shown in this video: www.flippingphysics.com/conservation-of-momentum.html If the net external force acting on the system equals zero, then linear momentum is conserved for the system, regardless of how many objects are in the system.

If there is a problem about Force of impact, what would be the example? (i.e. problem about explosion(?) problem about collision (?) ) Thank you!

At 1:04 before you implement the product rule, you first have to identify that whether both the mass and velocity function of time is continuous, otherwise it is meaningless to take the derivative.

Hey! I first want to thank you for the resources your provide! I wish to deepen my understanding of Calculus to have a better idea of what's going on hehe. However, I do have a question: My teacher claims that momentum is equal to change of momentum, is that true?

However, the testing conditions I had were worse and my proctor messed up my time as I was the one kid with extended time with 3 normal kids all taking a test at the same time. So! I would recommend talking to your AP coordinator at the school/ college prep person about that and find out the testing conditions to make sure to be prepared for the test!
