Homework Statement
I have to prove in a conservation of energy question
T-W =(mv^2)/L
mgL(1-cosO)=(mv^2)/2
mg=W
T=W(3-2Cos0)
How could I go about starting this?

To prove a cause and effect relationship, you need to conduct a controlled experiment where you manipulate the independent variable and observe the changes in the dependent variable. This will help establish a causal connection between the two variables.
No, correlation does not necessarily imply causation. Just because two variables are correlated does not mean that one causes the other. It is important to conduct further research and experiments to establish a causal relationship.
A control group is essential in an experiment to rule out other factors that may influence the results. By keeping all variables constant except for the one being manipulated, we can confidently attribute any changes in the dependent variable to the independent variable.
The strength of a connection between two variables can be determined by calculating the correlation coefficient. This is a statistical measure that ranges from -1 to +1, where 0 indicates no correlation, +1 indicates a perfect positive correlation, and -1 indicates a perfect negative correlation.
While it is possible to observe a correlation between two variables using observational data, it is not enough to establish a causal connection. To prove a connection, it is important to conduct controlled experiments where variables are manipulated and controlled to establish a cause and effect relationship.
