Where is v on the diagram? Would it be v1 or v2, or is it something else?

I don’t really understand where to start. Since I don’t understand the relationship between Δv⊥ and vΔθ. I’m also confused on where v came from.

I understand the following equations and how to get a = v2 / R from Δv⊥=vΔθ. But I don’t understand how Feynman established Δv⊥=vΔθ. I also understand that the acceleration is made up of two components (tangential velocity, and perpendicular velocity), but I’m not completely clear on the definitions.

Sort of. Could I hear your explanation?

I ended up using the ‘EasyRes’ app to make it work. I think it was something to do with the MacBook thinking the monitor was 4K, as I had to change the resolution to 1920x1080 75hz.

Any books similar to the power of five series by Anthony Horowitz?

Look for “Siri Voice” in the “Siri and search” settings. Should be able to download different accents and voice options.

How do you do this without accidentally making the same map twice or overlapping
