Energy Transformations

Question 3 • GA-GSE Physical Science B

The pendulum has the most kinetic energy [___].

Answer
A
at the top of swing
B
in the middle of swing
C
at the bottom of swing

Explanation

As the pendulum swings downward, gravitational potential energy changes into kinetic energy, so its speed increases. It moves fastest at the bottom of the swing, where its kinetic energy is greatest. At the top, it momentarily stops, so its kinetic energy is zero.
