Overall:
This week, through our usage of LegoMindstorm Experiment, we learned were able to learn about Newton’s 2nd law, the law of conservation of energy, velocity and acceleartion, and power.
Definitions:
Newton’s 2nd law – force = mass x acceleration
The law of conservation of energy – the total amount of energy in an isolated system remains constant over time. Also, energy cannot be created or destroyed.
Velocity – the speed of an object and a specific direction of the object.
Acceleartion – the rate at which the velocity of a body changes with time
Power – the rate at which work is performed or energy is converted
Program (we used in this lab):
Results:
| Mass (kg) | Acceleration (rpm/s) | Power Level (%) | Acceleration (rpm/s) | |
| 0.25 | 40.869839 | 100 | 89.66584 | |
| 0.2 | 42.477848 | 75 | 42.477848 | |
| 0.15 | 47.462272 | 50 | 16.984233 | |
| 0.1 | 65.160454 | 25 | 1.343651 |
Newton’s 2nd Law of Motion (F = mass x acceleration)
Law of Conservation of Energy:
(Potential Energy = mass x gravity x heightCalculations)
Power:
From this experiment we can analyze that;
1. As mass increases, acceleration decreases.
2. As power increases, acceleration increases
3. As matter increases, battery drainage increases
4. As power level increases, the power increases.
