Question

Assume that in the lab you proved that the period of the pendulum does not depend on its mass Which of the following parameters do you think you can account for in the prediction of the period of the pendulum using dimensional analysis?

2pi-correct numerical constant for the pendulum period

Force of friction in the air

g-acceleration of free fall

Theta0-launching angle

pendulum length

I-moment of inertia of the pendulum.

So I chose Length,2pi, and gravity. to get the equation period = 2pi* square root of L/g. However, I got both of those wrong.

If someone can explain why this is wrong with dimensional analysis that would be great.

2) What does the period of a pendulum depend on?

shape of pendulum bob

length of pendulum string

elesticity of string

iniital angle of the pendulum's swing

frictional forces (friction at the pivot)

strength of gravity

I chose intital angle of the swing, gravity and length and got it wrong, then chose gravity and length, but still got it wrong. Should I include friction at the pivot? If it's not ideal would my answer then be friction at the pivot, gravity and length?
