Today we conducted the lego experiment, which consisted of us having to use the Lego Mindstorm motor to control a pull to lift weights. By doing so we would or suppose to be leraning about velocity, acceleration, force, and mass.
Formula Used:
Force = mass x acceleration
F=ma
Heres a few things to keep in mind
In experiment #1 we made force a constant
We plugged the number 10 (10 being the constant force) into the program so the motor would lift the weight to that amount of force for each trial. We know that accelaration is dependent on the change in velocity or the change in distance over time, we wanted to see how acceleration changes at different levels of mass. To do so we change the weight five times to calculate those differences. See below for our results
Force (N) Mass (kg) A (m/s^2)
10 0.05 200
10 0.1 100
10 0.15 66.66
10 0.2 50
10 0.25 40
acceleration is calculated by diving velocity OR diving meters per second by second .
Equation
Acceleration = meters / seconds squared
A=m/s²
the lesser the mass, the greater an object can travel in a shorter amount of time, our chart above proves just that. To put it in more “scientifically” acceleration is greater when mass is lesser. ( I sound smarter that way, huh)
Ok soooo moving on to experiment #2
For experiment #2 mass was kept constant at 0.25 kg at five different levels of force. We kept force the same as in experiment 1. See our results below
Force (N) Mass (kg) A (m/s^2)
10 0.25 40
20 0.25 80
40 0.25 160
80 0.25 320
120 0.25 480
The concepts we leaned in this experminet can be easily applied to real life scenarios. We see these concepts in everyday life! Cool Stuff!
As always thanks for reading! catch you on the next post!
