CONCLUSION OF UNIFORM MOTION PRACTICAL OUT COME
Answers
Answer:
For our final problem, we had to estimate the mass of two unknown objects that were placed in the bucket. We performed 3 trials to get an average of 101 rotations per minute. We solved for the X in the equation and found that the mass of the object and basket combined was 455g. The mass of the bucket was 79g, so we estimated that the object's mass was 376g. The actual mass of the object was 427g. This gave us an error percentage of 376g / 427 g which is 88% accurate with a 12% loss of accuracy. This result we obtained was using the trend equation we generated. Using the normal equation which is F= (MV2)/R would require us to find the velocity which was 4.12 meters / second, plugging into our equation gave us a Force of 5300 N roughly. Dividing this by the gravity constant of 9.8 gives us roughly 540 grams for the target weight of the unknown which is considerably off from our trend equation, giving an accuracy of 78% with a 22% loss of accuracy. This is because there are many other unknown factors and forces that could affect our results such as friction, human error, and wear and tear. Using a trend equation ( in our case, a Power Regression) was the best idea for this experiment.

Answer:
Uniform Motion:
Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.
Non Uniform Motion:
Definition: This type of motion is defined as the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.
Example of Uniform Motion:
If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant in every second.
Movement of blades of a ceiling fan.
Example of Non Uniform Motion:
If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.
The motion of a train.
hope it is helpful bro...
