Heat out of hot thing = Heat in to cold thing Linear momentum = mass x velocity Angular momentum = mass x velocity x radius Power = Energy/time Useful Constants Gravitational acceleration on earth (g) = 10 m/s/s 1 calorie = 4.2 Joules specific heat of water = 1 cal/g o C Multiple choice problems (4 pts each) The energy of a ball rolling up a hill for which the zero of GPE is at the bottom of the hill is: Entirely kinetic.
(a ball; rolling up; ) (the zero of GPE; is; at the bottom of the hill)
a ball the zero of GPE
rolling up is
