I’m trying to get through 11-6 section of Feynman’s Lectures on Physics, Vol 1, particularly explanation of acceleration vector calculation in his example:
It’s clear that acceleration vector equals
Δv/Δt, but calculation of its components (tangent and transverse) is obscure to me.
Maybe I’m missing some elementary math or some insight behind working with limits, but:
- Why tangent acceleration is
- How it even possible to multiply a vector by an angle (
- Do I correctly understand that
Δθ/Δtgives us an angle velocity and transverse acceleration is calculated as product of linear velocity times angular velocity (
Could someone please explain that?
