2-Oct-2014 Conservation of Energy #12

Purpose
The purpose of this lab is to measure the types of energy's with a spring and different sensors.
The types of energy's we will be covering along with there formulas are:

KE {Kinetic Energy} mass=1/2mv^2 (using motion detector)
PE {Potential Energy} mass=mgy(middle of mass)+constant=mgy(bottom of mass)
Elastic PE in spring= 1/2k(stretch)^2=1/2k(at rest spring-y(bottom of mass))
KE of Spring itself=1/2(Mspring/3)(Vend of spring)<------same as bottom Vbottom mass
GPE {Gravitational Potential Energy}of spring itself=constant+(Mspring/2)gybottom of mass
Total Energy in system: changes in oscillation

In these photos we attached the spring to the force sensor along with a motion sensor on the floor that will measure the distance that the spring is from the ground.

Then once everything is attached we measured the oscillations with logger pro to create a graph with the slope that we can use for our formulas.

Once established we input the formulas that were given to us and created a column for each designated formula then graphed them on a single graph in to get our total conservation of energy in joules.
