A swimming pool has more of this than a cup of water at the same temperature.
What is thermal energy
400
Location in a sound wave, where particles are packed tightly together
What is compression
400
Gravitational potential energy
What is a ball at the top of the hill, etc.

Why is it important for bridges to have expansion points?
As the bridge warms, it expands. As it cools, it begins to contract. If the bridge had no expansion joints it would not allow the bridge to expand or contract without breaking apart.

What is the doppler effect?
When a sound sun as a fire truck, approaches the sounds waves appear to move closer together producing a higher sound, but as the truck moves farther away the waves are further apart and have a longer distance to travel so they sound lower in pitch
