Energy trivia game show

Energy is...

The difference between an energy transfer and energy transformation is...

A wind up toy is wound up and then walks up a ramp. Describe all of the energy transfers and transformations as the energy flows causing changes in the object.

Draw an energy bar chart for the pendulum at position 4

A group has a bungee cord with a spring constant of 30 N/m. They calculated that the energy their doll will transfer into the cord as it falls is 80 Joules.

How much will the cord stretch?

A bungee jumper with a mass of 40kg and at height of 21 M jumps off a bungee ride. His bungee cord has a spring constant of 300 N/m

At the bottom of the ride, which is 1 m off the ground, what is the amount his bungee cord has stretched?

If the jumper from the previous question (jump height of 21 m) was 2 m tall, the string attached to the bungee was 7m long and the unstretched bungee cord was 4 m long, Did the jumper in the previous question (with a bungee stretch calculated at 7.3 m from the previous question) have a safe bungee ride? 

Why or why not? Show with numbers & drawings on whiteboard

An averaged sized sedan car is driving down the Interstate going the speed limit (60 mph). What is its approximate total kinetic energy?

The car from the previous question flies off a cliff that is 2000 cm high. What is its total energy it has at the moment it goes off the cliff if it previously had 474,000 J of Ek?
