Question

if a ball begins to roll down an incline, its ______ is converted into ______. multiple choice entropy, chemical energy heat, chemical energy potential energy, kinetic energy kinetic energy, potential energy

Explanation:

When a ball is at the top of an incline, it has potential energy due to its height (stored energy based on position). As it rolls down, it gains motion, so potential energy is converted into kinetic energy (energy of motion). The other options are incorrect: entropy is about disorder, heat and chemical energy don't relate here, and the last option reverses the energy types.

Answer:

C. potential energy; kinetic energy (assuming the third option is labeled C, with the text "potential energy; kinetic energy")
