In this video I will use the partial derivative with-respect-to x and v to find the Lagrangian of a mass attached to a spring.

Next video in the series can be seen at:

Wow, never made this connection before. Thanks for this example!

Why did we know that the time derivative of the partial differential of the Lagrangian with respect to v is equal to the partial differential with respect to x? Are we just plugging in the fact that we know F=ma? Doesn't make sense to me where that part came from.
