The best statement that describes the change in energy of the acorn as it rolls off the roof and falls to the ground is:
**The acorn’s potential energy decreases as its kinetic energy increases.**
This is because as the acorn falls, it loses height (thus decreasing its potential energy) and simultaneously its velocity increases (thus increasing its kinetic energy).
**The acorn’s potential energy decreases as its kinetic energy increases.**
This is because as the acorn falls, it loses height (thus decreasing its potential energy) and simultaneously its velocity increases (thus increasing its kinetic energy).
