Chapter 7 - Kinetic Energy and Work –Summary
 
1.KE = ˝ mv2   (J)
2.
2.Work = Transferred Energy (to object +, from object - )
3.
3.Work done By Constant Force = F•d
Wnet = (SF)•d= F1•d + F2•d +..= W1 + W2+ …
4.
4.Work and KE ŕ DK = Wnet
5.
5.Wg = Fg•d = mg d cosf
6.
6.Work done by variable force
W = ∫ Fx dx + ∫ Fy dy + ∫ Fz dz
7.
7.Ws = ˝ kxi2 - ˝ kxf2
8.
8.Power, Pavg = W/Dt  (W)
P = dW/dt
P = F•v = F v cosf
