- Q1Which of the following statements is true?The work done by a conservative force depends only on the beginning and ending positions of the object.If a force does positive work on an object, then the stored energy of the object increases, and vice versa.The work done by a non‐conservative force does not depend on the path of the object.Friction cannot dissipate energy as heat and as sound.30s
