Question

Draw one complete swing of a simple
pendulum. Mark the point(s) with the
greatest kinetic energy and the point(s)
with the greatest potential energy.​

Answer 1

Kinetic energy is defined as

$Ek = \frac{1}{2} mv {}^{2}$

Since the mass of the pendulum bob won't change, the only way for kinetic energy to change is for the speed of the pendulum to change. Kinetic energy is highest when the velocity is the highest. This occurs at the bottom of the pendulum.
