johanna is studying what happens to the energy as a ball rolls down a ramp. what is one form of energy that she is studying?
gravitational potential energy
electrical energy
chemical energy
elastic potential energy

Explanation:

When a ball rolls down a ramp, it is affected by gravity. Gravitational potential energy is the energy an object has due to its height in a gravitational field. As the ball descends the ramp, its height decreases, and gravitational potential energy is involved in the energy transformation (converting to kinetic energy as it moves). Electrical energy involves electric charges, chemical energy is related to chemical reactions, and elastic potential energy is for objects that can be stretched or compressed (like springs). None of these are relevant to a ball rolling down a ramp in the context of basic energy transformation due to height change.

Answer:

gravitational potential energy
