4 cards from this section. Quick, good the night before a test.
Define mass conservation in your own words.
Think about what happens to mass in a closed container.
What happens to energy in a closed system?
Remember the example of energy conversion in machines.
Is mass conserved in a closed system?
Think about an unsealed and sealed container.
What does momentum conservation state?
Consider the formula relating force and momentum.
A closed loop system continuously pumps water in and out but loses some volume due to leaks. How does mass conservation apply in this scenario?
Think about how inflow balances outflow and leaks.
Consider a turbine generating energy from flowing water. If the water’s speed increases, what happens to the energy your system is producing? Discuss this in the context of energy conservation.
Recall how energy changes form as it moves through systems.
