Question

conservative and non conservative forces?

Answer 1

Hello!

Here is your answer!
==========================================================

Conservative forces:-

1) A force is said to be conservative if work done by the force or against the force to move an object through a certain distance depends only upon the initial and final positions of the body not on path followed by the object between initial and final positions.

2.) it is a gravitational force

3.) it is always zero


Non conservative forces:-

1.)  A force is said to be non conservative force if work done by the force or against the force to move an object through a certain distance depends on the nature of the path not on the initial and final positions.

2.) it is a frictional force.

3.) it cannot be zero.

Hope it helps!

Answer 2

if work done by the force acting on a body depends on the path followed by the body , force is said to be
non-conservative.
for example -frictional force.


if work done by the force acting on a body does not depend on path followed by the body , force is said to be conservative.
for example - gravitational force.
