My classmate Abdulrahman and I were given robot parts to build according to the instruction in one class, and we had to make it moving backwards and forwards . In the next class, we continued working on the robot we built to perform certain tasks. Lecture was given on distance, velocity, and acceleration. One of the most important tasks was to connect the robot to the PC and program it in order for it to perform. We measured the circumference of the wheel, which was 0.1760m, to determine how far it can travel in one complete rotation of the turn. By programing the robot different numbers of power due a constant time, the results of rotation, number of wheel turns, velocity, and distance will change directly proportionally. The following table illustrates the relationship previously described.

Time= 1s
Circumference of the wheel= Pi* wheel diameter = 0.1760m
With time being constant at 1 second, velocity and distance are always equal according to the famous formula: velocity= distance/time.
Conclusion, although it was more of entertaining activity, it was very informative and encouraging in way that connects my preference in doing physical work with physics.
The essay incorporated the steps needed for the experiment.The student could clearly express himself and explain the experiment clearly.Every calculation mentioned in the essay was supported by its rule.I liked the fact that the student organised his calculations in a table which made it easier for me to understand the results for each trial. Overall,the blog is well constructed.
