September 24th’s lab experiment consisted of calculating potential energy and acceleration. First we created a pulley by attaching weights to a wire wrapped around a wheel. We connected the robot to the computer in order to control the mass, speed, time, etc. and track our results. We first kept the force constant at 10 newtons and saw how it was affected by the weight change starting at .05 kg up to .25 kg. Later we kept the mass constant at 0.25 kg and tracked how it affected force and acceleration when force increased each time by 10.
This is what we came up with when we kept the force constant:
| Force | Mass | Acceleration (m/s2) |
| 10 | 0.05 | 200 |
| 10 | 0.1 | 100 |
| 10 | 0.15 | 66.66666667 |
| 10 | 0.2 | 50 |
| 10 | 0.25 | 40 |
This is a graph of our results mass on the x axis and acceleration on the y axis.
This is what we came up with when we kept the mass constant:
| Force | Mass | Acceleration (m/s2) |
| 10 | 0.25 | 40 |
| 20 | 0.25 | 80 |
| 40 | 0.25 | 160 |
| 80 | 0.25 | 320 |
| 120 | 0.25 | 480 |
These are our results for potential energy
| Potential Energy | Mass | Height |
| 0.1127 | 0.05 | 0.23 |
| 0.2254 | 0.1 | 0.23 |
| 0.3381 | 0.15 | 0.23 |
| 0.4508 | 0.2 | 0.23 |
| 0.5635 | 0.25 | 0.23 |
