Kinetic Energy in Polar Coordinates (8.4)

In this video, I derive the kinetic energy in polar coordinates, pursuant to the study of planetary motion.

Excellent 👌🏻

Your explanations emphasize clarity by attention to details and clear explanations! Great job, sir!

[@pervazmushara]

Good explanation ❤

6:40 (until the end) He uploaded this just before Easter and took a few days off after this, hahaha! Well done, sir.

I Love Your your Teaching Style :)

I think you missed out the derivative of psi on the cross product, isn't supposed to be -2r'r psi' sin psi cos psi? same goes with the +2r'r psi' sin psi cos psi I know it eventually cancels out and I doesn't really matter but I thought I point it out since I thought I missed out on something

Thank you sir !

There is no kinetic energy in a moving mass there is force Mv squared , kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers

[@jameyatesmauriat6116]

I don’t understand, so what’s wrong about the demo?

[@grahamflowers]

Mass is a constant only velocity is a variable regards Graham Flowers
