Question

Which statement explains the energy exchange in a clock's pendulum?(1 point)
Responses

When the pendulum swings upward, it gains potential energy that is changed to kinetic energy as it swings downward.
When the pendulum swings upward, it gains potential energy that is changed to kinetic energy as it swings downward.

When the pendulum swings back and forth, the energy gained is used by the clock's hands.
When the pendulum swings back and forth, the energy gained is used by the clock's hands.

When the pendulum is motionless, it gains potential and kinetic energy.
When the pendulum is motionless, it gains potential and kinetic energy.

When the pendulum swings back and forth, it uses potential energy

Answer 1

When the pendulum swings upward, it gains potential energy that is changed to kinetic energy as it swings downward.

Answer 2

to overcome the force of gravity and kinetic energy to continue swinging.

Answer 3

Correct! As the pendulum swings upward, it gains potential energy due to its height above its resting position. As it swings downward, this potential energy is converted into kinetic energy, or energy of motion, which causes the pendulum to swing back up again. This exchange of potential and kinetic energy allows the pendulum to continue swinging, which in turn powers the clock hands.
