| Simularea | Masses & Springs |
| Cuvinte cheie | springs |
| Descriere | Learning Goals Students will be able to explain how the displacement of a spring at rest is related to the mass of the object on the spring (which is called Hooke's Law). Students will be able to use the displacement of a spring at rest to determine the mass of unknown objects. Students will be able to explain how the displacement of a spring at rest is related to the acceleration of gravity of the planet the spring is on. Students will be able to use the displacement of a spring at rest to determine the acceleration of gravity of an unknown planet. |

- it seems like somethings broken - or i'm not using it right. when i hang twice and then five times the weight - i don't get exactly twice and five times the displacement? It's a little less than 5 for 50 grams, a little less than twice (4.5) for 100, a little less than 5x (4.50 for 250. notes from other teachers indicate, as expected, exactly 5,10 and 25? could it be my browser or something? 22.02.2011
