When the PPF graph bows outward it usually means that, as the production of one good continues to grow, the opportunity cost of producing another good increases
A Production Possibility Frontier (PPF) is a curved bowed out from the origin. It is mostly 2 dimensional and involving 2 goods or services.
The shape of the PPF has to do with how many units of good A you have to give up to get another unit of good B It is related to how those goods are different in the types and amounts of productive resources between the two goods. The PPF is straight when you have to give up one unit of good A to get another unit of good B.
The production possibility curve is not always linear, in fact, it is usually concave down (bowed-in). The shape of the curve depends on the substutability of the goods described by the curve in the question. When goods are perfectly substitutable in production, the PPP (or PPF) is linear.
economic growth, will shift the PPF outward, because the income will increase.

The PPF is bowed outwards (concave to the origin) as tradeoffs between the production of any two goods are constant.

When there are diminishing marginal returns to factors of production, the PPF is "bowed out" from the origin.

it represents the boundary between the goods that are attainable and unattainable within an economy. Inside and along the ppf means that goods are attainable and outside the ppf menas the goods are unattainable and it thereby shows scarcity
An increase in resources, such as a growth in the labor supply or in the capital stock, shifts the frontier outward.
War has two distinct effects on the PPF of a nation. Assuming the homeland of the nation at war were vulnerable to attack the entire PPF would shift inward as factories fell prey to enemy attacks - this was not the case for the US during WWII. WWII did not cause an inward shift of the PPF for the US because the mainland was not subject to attack. Production in the US was subject to the second effect of war on the production of a nation, the productive resources were shifted toward materiel for the war effort. This is not an outward shift of the PPF in any way, it is a movement along the PPF in favor of war machines at the cost of consumer goods. It is this second effect that enables countries to produce more war goods despite shrinking overall productivity than the country did in peace.To reiterate, you must remember to treat the two effects of war on a nation's PPF separately because they are distinct effects. Changes in the overall PPF are a result of acts of war (e.g. bombing factories) whereas movements along the PPF are the result of being in warfare (i.e. a given factory now produces tanks instead of cars
A PPF shows the maximum amount of goods that can be produced with a given set of inputs.
