Question

characterizing energy relationships
when you view the pendulums swing, it shows that at
the very top of the swing ke = 0. what does that tell you
about the pendulums motion at that point?

Explanation:

Kinetic energy (KE) is given by the formula \( KE=\frac{1}{2}mv^{2} \), where \( m \) is mass and \( v \) is velocity. If \( KE = 0 \), then \( v = 0 \) (since mass \( m>0 \)).

Answer:

The pendulum is momentarily at rest (velocity \( v = 0 \)) at the very top of its swing.
