Homework Help Overview

The discussion revolves around a lab experiment aimed at determining the acceleration due to gravity (g) using a simple pendulum. Participants are examining the rearrangement of the formula T = 2π√(L/g) to isolate g.

Discussion Character

  • Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to rearrange the formula but questions the correctness of their manipulation. Other participants provide feedback on the rearrangement process and suggest methods for isolating g.

Discussion Status

The discussion is ongoing, with participants providing insights into the algebraic manipulation required to isolate g. There is a focus on ensuring that the mathematical operations are applied correctly, but no consensus has been reached on the final form of the equation.

Contextual Notes

Participants are working within the constraints of a lab assignment, which may impose specific requirements for the rearrangement and presentation of the formula. There is an emphasis on understanding the correct application of mathematical principles in this context.

I am doing a lab on finding g using a simple pendulum experiment.

the formula is:

T = 2pi sqrt(L/g)

how is that rearranged to find g?

I got g^2=2piL / T


is that right? thanks
 
Physics news on Phys.org
g = ((L)/((T)/(2pi))^2)
 
PIML,

You forgot to square the 2*pi
 
Just do the same things on each side.

e.g. if a = 1/b, then multiplying on both sides by b gives

ab = b/b = 1

ab = 1.

Similar for multiplication and to invert square root, simply square both sides.
