Thank you We sneak And here's your shmoop news your

00:06

brought to you by do it yourself spaceships but at

00:09

least finish ap physics before you try to build one

00:12

All right well if a spaceship came close toe earth

00:15

which of the following would be correct about situation select

00:18

to who These air right And here the potential answers

00:23

our spacious unaffected help Well one thing we know for

00:28

sure the earth has gravity Trust us We've tried to

00:31

just jump into space before and when we didn't get

00:34

very far That's because the earth has a lot of

00:36

mass which creates a lot of gravity and it's not

00:39

just the earth Anything that has mass also creates a

00:43

gravitational field So we know for sure that option a

00:50

is one of the correct answers Because earth has gravity

00:54

anything that approaches our planet will feel the pull of

00:57

gravity comments asteroids alien warship coming to enslave humanity well

01:02

none of them can escape gravity's like the overlord That

01:05

also means that we can eliminate option c there's no

01:08

way that's correct an option D no way Gravity wouldn't

01:11

repel the spaceship so that's wrong as well Now the

01:15

spaceship also has masked And remember when we said anything

01:18

that has mass also creates a gravitational field right So

01:22

if the spaceship has mass it has a gravitational field

01:25

that holes on the earth even if it's just a

01:29

tiny pole like an ant trying to move bowling ball

01:33

The spaceship is in fact exerting of force So our

01:37

second correct answer is option b Gravity is a two

01:41

way street Remember that when you're building the ss from

01:44

up And also remember building a spaceship is the easy 00:01:47.794 --> [endTime] part Buying rocket fuel pontes a lot harder
