The period of a simple pendulum, defined as the time necessary for one complete oscillation, is measured in time units and is given by
Where l is the length of the pendulum and g is the acceleration due to gravity, in units of length divided by time squared. Show that this equation is dimensionaly consistent. (You might want to check the formula using your keys at the end of a string and a stopwatch.)
1) What are the dimensions of g?
2) What is the dimension of sqrt(l)?
The solution explains in words the solution to the problem. The solution is 40 words.
