What is the name for stored energy?
Potential energy
In Newton's Cradle, why don't the balls keep moving forever?
A little bit of the energy is lost each time there is contact between the balls.

What simple machine was used in the Pteranodon Automaton Project?
Lever (wheel and axle is also an acceptable answer)
What is the formula for momentum?
Weight of an object multiplied by it's speed
(mass x velocity = momentum)
Why wouldn't a parachute help a lunar lander land safely on the moon?
There is very little atmosphere on the moon, which means there isn't enough air to create lift and slow it down.
Why is it important for engineers to consider friction in their designs?
Example answer: Friction slows down moving objects and creates resistance, which can impact the energy or functionality of a design.
