Question

Conservative of aplly to gravitational Forceearth

Answer 1

Answer:

Yes, A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the taken path

Explanation:

Now taking the example of Gravitational Force. Suppose we throw a object of mass ‘m’ upward suppose it goes up to a height h.

then the work done in throwing object in upward direction w1 = -mgh (use ‘-g’ sign convention )

and the work done while returning to the same path w2 = mgh

total work done W = w1 + w2 = -mgh+mgh = 0

Hence, total energy loss will also be zero in this case.

So, Gravitational Force is Conservative Force.

It won’t be the same case if any friction is present, there will be some mechanical energy loss due to friction.

Therefore, friction is a non-conservative force.
