Question

Which of the following objects has more kinetic energy than it does potential energy? Select the correct answer below:______1.a compressed spring in a pinball machine just before the ball is launched a rollercoaster motionless at the top of a track a yo-yo before it is released the pendulum of a grandfather clock at the lowest point of its arc of motion

Answer 1

Answer:

The pendulum of the clock.

Explanation:

Hi there!

The kinetic energy is the energy associated with the velocity of the object. The potential energy is the energy associated with the position of the object. In the objects listed in the question, only one object is moving: the pendulum of the clock (assuming that the clock is functioning). If the clock functions, the pendulum is moving when it is at the lowest point of its arc of motion and with maximum velocity. All potential energy that the pendulum stored when it reached the highest height, is transformed into kinetic energy at the lowest point. Thus, at that point, the object has more kinetic energy than potential energy.
