Solution
Solution Steps
Step 1: Identify the Initial and Final Forms of Energy
When a ball is at the top of a hill, it possesses potential energy due to its elevated position. As it rolls down the hill, this potential energy is converted into another form of energy.
Step 2: Determine the Energy Conversion
As the ball rolls down, the potential energy is converted into kinetic energy, which is the energy of motion.
Step 3: Match the Conversion to the Given Options
From the given options:
A. Potential energy to chemical energy
B. Chemical energy to kinetic energy
C. Potential energy to kinetic energy
D. Kinetic energy to potential energy
The correct conversion is from potential energy to kinetic energy.
Final Answer
\(\boxed{\text{C. Potential energy to kinetic energy}}\)
