The ‘dead air’ space between the panes of glass is a poor conductor of
heat.
Elastic Materials
• All materials have some elasticity to them. Some just more than others.
• Ability to bend and recover before breaking.
Pneumatics

How was the potential energy of the spring transferred to the wheels?
How to Calculate a Gear Ratio
• Number of Teeth on one gear divided by the Number of teeth on the other
• Or diameter of one pulley divided by the diameter of the other.
