Question
1) What if the track had been considerable off level? How much energy would have lost to work against gravity as M traveled a distance h down the track when the track slanted uphill at some angle theta? By how much would v2f be reduced ? (note : You do not have to put any numbers into the equations). 2) Can you say that you have"proved" the work energy theorem to be true? Why or why not? If you experienced these lab questions, please help me out answer these questions. You can answer as much as you can. I appreciate your help. 1) What if the track had been considerable off level?

Given that mass M is travelled at a distance h down the track. and slanted at an angle ? The work done aganist the gravity is W = F * h cos ? = m g * h cos? Using work energy principle W = ? K.E = 1/2 m ( v_f ^2 - v_0 ) ^2 v^2 = 2 * W / M v = v 2 * W / M b ) Let the total net work W _net as a sum of Work done by conservative and non conservative forces W _net = W _C + W _NC using work energy principle W _net = ?K.E W _C + W _NC = ? K.E W_NC = ? K.E - W_C W_C = ? P.E W_NC = ?K.E + ?P.E Thus , the Work done by non consevative acting on the object is equal to the total change in kinetic and potential energyRelated Questions
