| | ==== Project 2A: Chasing a Thundercloud ==== |
| | |
| | You and your group are a team of storm chasers tracking a massive thundercloud moving across the plains and into the mountains beside the town of Lakeview. You grab your handy-dandy high voltage probe ([[https://www.atecorp.com/ATECorp/media/ProductImages/L/Tektronix-P6015A_L.png|like this one]]) and radio, then drive from your headquarters 250 m until you are directly under the storm cloud. Thankfully, your team already calibrated the voltmeter to 0 V when the storm cloud was very far away. From your training, you know that if the electric field is bigger than 3 MV/m (also called the [[https://en.wikipedia.org/wiki/Dielectric_strength|dielectric breakdown of air]]), the air will become a conductor and lightning will strike. You need to determine if a) you are safe from lightning under the thundercloud and b) if the lightning rod on top of the storm-chaser headquarters will be hit. The master storm chaser and part-time civil engineer, Edric Storm, tells you that the storm-chaser headquarters is 200 m tall. |

| | ===Learning Goals - Project 1A:=== |
| | * Understand what the $\vec{r}$ is, how to calculate it, and how it relates to $\hat{r}$ |
| | * Become familiar with the ideas of electric field and electric potential |
| | * Explain the differences between electric field and electric potential |
| | * Explain how electric field and electric potential are related |

| | ==== Project 2B: Meanwhile Back At Stormchaser HQ==== |
| |
| The team back at headquarters has just received a call from the National Weather Service (https://www.weather.gov/) that they want you to take some additional data on this cloud. Apparently some of the properties of this cloud are particularly interesting, specifically due to the fact that the cloud is moving Northward, not typical of most clouds in this geographical region (see some [[https://www.physicsforums.com/threads/why-do-clouds-move-in-a-certain-direction.757627/|discussion of this here]] if you're interested). For the moment, the winds have died down and the cloud isn't moving. | The team back at headquarters has just received a call from the National Weather Service (https://www.weather.gov/) that they want you to take some additional data on this cloud.
