How to take the time derivative of a potential gradient ?

Pet Scan · Dec 2, 2016

I am not that great at vector calculus , etc.
Can someone show me how to take the time rate of change of a potential gradient? (Not homework)
Thx.

Consider the gravity gradient above a planet. It's time derivative is practically zero. There is no a priori reason for a gradient to have a time rate of change.

So your question makes no sense without more information.

Just to clarify...I didn't say a gravitational gradient. How about an electric potential gradient?

OK, why do you think it has a time rate of change?
