| Now that we've created a room without friction let's see what happens if we swing a giant pendulum! | |
 | |  |
|
 |
| | |
| Sure! What's the worst that could happen? | |
| | |
|
|
|
|
|
|
|
| | |
| Perhaps we should have thought this through a bit more. | |
| | |
|
 |
| | |
| Without friction a pendulum wil continue to move back and forth, as it is a simple harmonic oscillator. | |
| | |
|
|
|
|
|
|
|
| | |
| This continues forever, unless the pendulum reaches its equilibrium position. | |
| | |
|
|
| | |
| Without friction the only way that can happen is if someone exerts an equal amount of force to make it stop. | |
