Explain how your observations support the conservation of energy

• As one energy store goes down the other goes up, and so the total energy of the system stays the same

• Energy keeps increasing

• The energy is destroyed

• There is twice the energy at the end than at the start

Where in its swing does the pendulum have its largest gravitational potential energy store?

• At the ends

• In the middle

• Somewhere in between

Where in its swing does the pendulum have its largest kinetic energy store?

• At the ends

• In the middle

• Somewhere in between

In which of the three positions is the jumper's gravitational energy store largest

• Position 1 - waiting to jump

• Position 2 - rope unwound

• Position 3 - lowest point before he rebounds
