This in turn does not add a greater gravitational pull downward due to the greater level of mass. Which means that the string has added tension, which pulls the cart faster in table number 2. How does the acceleration in Data Table 3 compare with that of Data Table 1? Why do we observe this difference? In data table 3 the rate of
Productivity is also lowered because those few minutes spent changing clocks could have been spent doing something else, like homework. Plus, the loss of sleep reduces concentration and brain processing speed, meaning tasks take longer to complete. It’s estimated that every time the clocks are changed, the US economy loses almost half a billion dollars! That lost hour of sleep does more though, as there are well documented health issues that arise due to a lack of sleep. The two most
Since the plastic container had a greater amount of GPE when rolled from a higher starting ramp, this was converted to a greater amount of kinetic, or moving, energy when rolling down the ramp. So, with the tallest starting ramp height, the plastic container had the the most kinetic energy. Due to having the greatest amount of kinetic energy, it had the most moving inertia, or momentum in the middle at the bottom. Newton 's first law states that a body at rest stays at rest and s body in motion stays in motion unless after upon by an unbalanced force (inertia). In this case, the unbalanced force is rolling friction, and it always stayed the same throughout this experiment.
The biggest limitation is the differences in their experimental conditions. The waitlist condition lasted only half as long as the treatment condition. Although the 12-week waitlist is methodologically preferable, the board deemed it unethical to withhold treatment from this population for that long. Perhaps within 12 weeks, more waitlisted patients would have shown improvement; future research should account for this limitation. Furthermore, their small sample size also limited the research.
There are a couple reasons why it had to close. One reason of why it closed was because the reason was getting expensive. Another reason of why it closed was because the island was wearing off, the rocks were going through erosion. The last reason of why they shut down Alcatraz was because the prison wasn 't secure. A lot of prisoners were escaping, which was a bad thing.
From line 8, however, is where we struggled most. I had difficulty with some of the vocabulary but after some research, we were able to understand that the double-dagger poles of power companies were simply power lines and they were replacing the previous image of the trees that the passengers had previously seen in hindsight. We had trouble with line 10 because the usage of the words footnotes did not seem to fit the poem the way we felt it should have. As Nina said, “In a formal paper it is [footnotes] used to cite or further explain something.” Anna had an “ah-ha” moment and in the process of explaining, lost both Nina and myself. Repeating the lines and elaborating a little more helped both of us understand.
From our first rocket, we discovered that we had to be more sparing regarding the outside design elements on the projectile. The feathers we had constructed from colored paper and then attached to the body and wings of the rocket had weighed it down, increased air drag, and inhibited the possibility of a successful launch. From that experience, we knew not to put so much extra elements onto the body of the rocket in order to promote a smooth flight. Overall, the first rocket that was crafted was far too heavy, and when water was added to it, the projectile’s mass was overbearing thus reducing the height and travel time of the launch. The first bottle rocket we had made this year taught us many lessons regarding beneficial construction techniques, and provided guidance for the manufacturing of our second
When moving an object across a floor, we need to use a large amount of force because of friction. Friction is the force resisting the motion. Because a wheel turns instead of slides, the friction acting upon the wheel is less than if we tried to slide the object. Because there is less friction, there is less force needed to move an object the same distance.
The faster an bject moves the more kinetic energy it has. The kinetic energy increases as its mass increases. Potential energy is stored energy, which means that an object can have energy even if it is not in motion. Some other forms of this energy include gravitational potential energy, elastic potential energy, and chemical potential energy. Friction is the force that resists the motion of two surfaces sliding against one each other.
Also we thought that coiling the wire was very difficult and that it was not the wire that was the issue with why our experiment was not working. After we started to change all of the variables and our experiment still did not seem to have positive results we decided that maybe our coils were the issue. We then recoiled the wire around a smaller object and got it come up with a reaction with the multimeter. Making sure that the coils were only slightly bigger than the batter we sent the battery through the copper wire and let it sit trying to think of more ways to make this work. After letting the battery sit inside of the wire we pulled out the magnet to find it to be warm, it was not like the battery was super hot and was going to catch on fire or anything it just seemed to be warmer than it was when we inserted it to the copper coiled
