When a pendulum swings, at which point is kinetic energy highest?

• 1 because it's at the highest point so it has the most stored energy

• 2 because it's getting faster as it goes down

• 3 because at the bottom it is going the fastest

• 4 because as it starts to go back up it begins to slow down
