Consider the net force on the system.quietrain said:to tell the truth, i don't know :(
I'd put it this way: The only way to accelerate the system is by using an external force. (Internal forces will just cancel out.)quietrain said:ah i see...
so there's no way that internal forces can ever make the system do work? only an external can?
No, uncertainty cannot be completely eliminated. Uncertainty is a natural part of life and is present in every scientific problem. However, it can be minimized through careful analysis and consideration of all available data and evidence.
Uncertainty in scientific research can be dealt with by using statistical methods, conducting further experiments to gather more data, and by being transparent about the limitations of the research. Collaboration with other scientists and peer-review can also help to reduce uncertainty.
Some common sources of uncertainty in scientific studies include measurement error, sampling error, and human error. Other sources can include limitations in technology, complexity of the problem, and external factors that may affect the results.
Communicating uncertainty to the public is important to maintain transparency and avoid misunderstandings. Scientists can use visual aids, clear language, and provide a range of possible outcomes or confidence intervals to convey uncertainty. It is also important to acknowledge what is known and what is still uncertain.
Yes, uncertainty can lead to incorrect conclusions if it is not properly addressed and considered in the research process. It is important for scientists to carefully evaluate the level of uncertainty and account for it in their analysis and conclusions. Communication and collaboration with other experts can also help to reduce the risk of incorrect conclusions.
