WHY will the object loses energy ???the energy is conserved...
A conservative force is a force with the property that the work done in moving a particle beeen o points is independent of the path taken. The direction beeen the action of the force and that of the path has no relation to the definition of "consevative force". Gravitational force is a conservative force because it satisfies the above definition. For example
an object that falls vertically by a height of 1 metre
say
under the action of gravity loses the same amount of energy as the same object that slides down a *** ooth inclined plane with a vertical fall of 1 metre. 2012-01-31 20:16:12 补充： Q:WHY will the object loses energy ???the energy is conserved... A: The object loses potential energy
but gain in kiic energy. The total mechanical energy is conserved.
