Introduction:

In the third experiment that we have done in class with the robot is to use a pulley to compare and graph their accelerations using power through labview and mass through a ruler measurement. It also involved examining Newton’s 2^nd Law (F = ma) and into the conservation of energy.

 

Here is a picture of our experiment:

 

Procedure:

For the first experiment, we kept the force (power) at a constant level and only changed the mass of the object been picked up acceleration changed. By theory, when started with the lowest weight, and then increased it with the other try’s, the heavier the mass the less acceleration it produced with the same amount of force (power). And it worked.

Mass	Acceleration
0.19	394.74
0.14	535.71
0.09	833.33

 

 

 

In this second part of the experiment, we kept the mass steady, and just increased the force (power) of the LEGO motor the acceleration here would change with a positive relationship with the change of the force being incremented. For example: we kept a steady mass of 0.1 kg, and started with a force of 100 decreasing each run by 25.

Conclusion:

 

I had fun with this lab and it was a successful lab. I work an electrical devices and a pulley to prove the newton 2^nd law. First we had to measure the power, then mass with acceleration and graphed it to confirm that each does what they were suppose to do.
