| Front | What happens to an atom when it emits EM radiation? |
| Back | Electrons fall back down to ground state, losing energy by emitting radiationThis means electrons move closer to nucleus and move to lowere energy level |

| Front | State an equation to find energy transferred in stretching. Include units. (This is included in exam so just learn how to use it) |
| Back | Energy Transferred in Stretching (J) = 0.5 x Spring Constant (N/m) x Extention2 (m2)E = 0.5 x k x x2E = energy transferred in stretchingk = spring constantx2 = extention2 |
