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

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

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

Answer 1

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

Explanation: As it falls, gravitational potential energy is converted into kinetic energy, so the PE goes down while KE goes up (neglecting air resistance, total mechanical energy is conserved).
