Question

question 1 points 2
a 2 kg object is raised 5 meters and then released. which of the following explains the energy transformation that occurs as it falls?

chemical energy turns into electrical energy

potential energy is stored and remains unchanged

potential energy transforms into kinetic energy

kinetic energy turns into potential energy

Explanation:

When an object is raised, it gains gravitational potential energy (due to height, formula \( PE = mgh \)). When released, as it falls, height decreases (so PE decreases) and speed increases (so kinetic energy \( KE=\frac{1}{2}mv^2 \) increases). So potential energy transforms into kinetic energy. The other options are incorrect: chemical to electrical is unrelated, PE doesn't remain unchanged, and KE to PE would be if object was moving up, not falling.

Answer:

Potential energy transforms into kinetic energy (the option with this text, e.g., the third option in the list: "Potential energy transforms into kinetic energy")
