Question

question 4
which statement is the best elaborates on the evidence?
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 cannot be created or destroyed, only converted from one form to another. The best - elaborated statement should explain this conversion in the context of the skater's motion on the half - pipe. The first option just says the total energy doesn't change without explaining the conversion. The second option only mentions adding kinetic and potential energy to total energy without emphasizing the conversion. The fourth option correctly states that energy is not lost but changes from potential to kinetic energy, elaborating on 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.
