Question

18) According to principle of conservation of energy under which type of force the
sum of K.E. and P.E. of a particle remains constant?
a)conservative Force
b) Non Conservative Force
c) Frictional force
d) viscous force​

Answer 1

Answer:

b is the answer for this

Answer 2

a)conservative Force

When a force's work on an item is irrespective of the object's path, it is called a conservative force. Instead, the work being done by the a conservative force is limited to the motion's end points. Gravity is a sample of a conservative force.

In other words, if the work done across any closed path is zero, a force is conservative. A non-conservative force that whose work is contingent on the path taken.
