Question

(i) claaaify the following into conservative and non conservative spring force, human push, gravitational force, viscous drag (ii) potential energy of a system due to a conservative for F is U. What is therealtion between then?

Answer 1

Dear Student ,
(i) Spring force , gravitational forces are classified as conservative force .
Whereas the human push and the viscous drag are classified as non - conservative force .
(ii) The relation between the potential energy U and conservative force is ,
$F=-\frac{dU}{dx}$
