Question

which statement is the best to restate the question?
○ this video supports the law of conservation because
○ the total energy does not change.
○ as the skater moves across the half - pipe the kinetic and potential energy add up to the total energy.
○ this supports the law of conservation of energy since energy is not lost but changes from potential to kinetic energy.

Explanation:

The law of conservation of energy states that energy is neither created nor destroyed, just converted between forms. The best restatement should capture this essence. Option 1 doesn't fully explain the law. Option 2 just mentions total energy without form - conversion. Option 3 only says kinetic and potential energy add up to total energy. Option 4 correctly states that energy is not lost but changes form, which is the law of conservation of energy.

Answer:

This supports the law of conservation of energy since energy is not lost but changes from potential to kinetic energy.
