If air resistance is considered,time of flight increases

OpenStudy (anonymous):

True.

OpenStudy (anonymous):

why

OpenStudy (lollylau):

It's pushing you BACK, that's why

OpenStudy (anonymous):

Because the air acts as a kind of obstacle. Due to friction, it reduces the speed by a very minute amount. So as speed decreases, time increases. But this is a very negligible amount.

OpenStudy (anonymous):

so shouldn't it decrease

OpenStudy (anonymous):

No

OpenStudy (lollylau):

You move, air resistance is there.

OpenStudy (anonymous):

Yes.

OpenStudy (lollylau):

Anywhere you move to.

OpenStudy (anonymous):

It slows you down all the time, without you noticing it.

OpenStudy (lollylau):

Where there is air/some "air" thing

OpenStudy (anonymous):

if it slows so it means that time has decreased

OpenStudy (anonymous):

No, time and speed are inversely proportionate. So time INCREASES.

OpenStudy (anonymous):

ok . understood . thank you
