As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy? 

• The PE and KE increase and decrease together
• The PE decreases while the KE increases 
• Impossible to know without knowing the mass  

What kind of energy does an object possess when it's resting on top of the hill?
