Question

2) Which combination of statements is most accurate? [Enter your answer as a string of the letter options you believe are correct. For instance, if you think options A, D, and E are correct, then enter "ADE". NOTE: There are only 5 tries for this problem.]

A) Increasing the separtion between two massive objects increases the GPE of their interaction.

B) Steadily lowering a ball to the ground decreases GPE while the ball's KE stays constant.

C) Energy conservation means that if a system is isolated, its total energy is constant.

D) Momentum conservation and energy conservation are independent principles of physics.

E) None of the above

Explanation / Answer

As GPE is inversly proprtional to distance That's why a is correct

Lowering the ball steadily means acceleration is zero means K.E is constant but G.P.E will increase as distance decrrdec by lowering the ball so B is incorrect.

C is correct and D is also correct
