Energy Book-keeping E2 - E1 = WNC
E Energy h x UG K US US= 0 UG= 0 = Mgh =½ kx2 = 0 E=US+UG+K E1= ½ kx2+0+0 E2= 0+Mgh+0 E2 – E1 = WNC E1= E2 ===> ½ kx2 = Mgh
E Energy v x UG K US US= 0 = 0 = 0 UG= 0 = ½ kx2 US= 0 K = ½ Mv2 UG = Mgx E2 = 0 + Mgx + ½ Mv2 E = US+UG+ K E1 = E2 ===> ½ kx2 = Mgx + ½ Mv2 E1 = ½ kx2 + 0 + 0
E1 E2 Energy v kx x Mg fk UG K US WNC = - fkx US= 0 = 0 = 0 UG= 0 = ½ kx2 US= 0 K = ½ Mv2 UG = Mgx E2 = 0 + Mgx + ½ Mv2 E = US+UG+ K E2 – E1 = WNC (Mgx + ½ Mv2)– ½ kx2 = - fkx E1 = ½ kx2 + 0 + 0
