characterizing energy relationships\nwhen 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?

characterizing energy relationships\nwhen 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?

Answer

Explanation:

Step1: Recall kinetic - energy formula

The kinetic - energy formula is $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity.

Step2: Analyze when $KE = 0$

If $KE = 0$, and $m\neq0$ (the pendulum has mass), then from $KE=\frac{1}{2}mv^{2}=0$, we can conclude that $v = 0$. A zero velocity means the pendulum is momentarily at rest.

Answer:

The pendulum is momentarily at rest at the very top of the swing.
