Is $r \times \frac{d}{dt} mv=\frac{d}{dt} (r \times mv)$

+1
−2

Is $$r \times \frac{d}{dt} mv=\frac{d}{dt} (r \times mv)$$

What is the result of a vector crossed with itself?

deleted user wrote over 3 years ago · edited over 3 years ago

$\vec v \times \vec v$ here $\times$ is cross product..... But, I can't see $\vec v \times \vec v$ in OP. I think you meant for cross product I have to differentiate both, didn't you?
