Experiment 4
Equations entered into the Equation Field of the Experimental Calculator:
Formulae for Momentum and Total Kinetic Energy:
• Total Momentum, Part A:
.51*@1.linVel*.01+.46*@3.linVel*.01
• Total KE, Part A: .51*(.5*(@1.linVel*.01)^2)+.5*(.46*(@3.linVel*.01)^2)
Formulae for smoothing data:
• Total Momentum, Part A (smoothed): smooth(8,Momentum1)
• Total KE, Part A smoothed:
.5*(.51*(smooth(8,@1.linVel)*.01)^2)+.5*(.46*(smooth(8,@3.linVel)*.01)^2)
