Question

An acorn rolls off a roof and falls to the ground. Which statement best describes the change in energy?(1 point)
Responses

The acorn’s potential energy is changed to mechanical energy.
The acorn’s potential energy is changed to mechanical energy.

The acorn’s potential energy and kinetic energy increase and decrease together.
The acorn’s potential energy and kinetic energy increase and decrease together.

The acorn’s potential energy decreases as its kinetic energy increases.
The acorn’s potential energy decreases as its kinetic energy increases.

The acorn’s kinetic energy increases until it hits the ground.

Answer 1

The best statement that describes the change in energy as the acorn rolls off the roof and falls to the ground is:

**The acorn’s potential energy decreases as its kinetic energy increases.**

As the acorn falls, it loses potential energy due to its decrease in height and gains kinetic energy as it speeds up.
