pension wants president limited All right well vectors can be

used to describe in calculate anything with magnitude and direction

on a vector field is a pattern of vectors in

space patterns determined by the distribution of sources that give

rise to the field This sounds like a riddle but

it's not just hang with us We don't mean to

be totally abstract here So let's try to simplify things

a bit Imagine a trampling with a bunch of marbles

sitting on it If the trampoline is left alone the

marbles won't go anywhere because of inertia They just sit

there doing nothing like a Now imagine what would happen

if we put a twenty pound weight in the middle

of the trampling Well since the trampling would now sag

toward the middle push down by the way the marbles

would roll and moved toward the middle due to gravity

Well the speed and direction of each marble is a

vector And if we plotted the vectors beach marble we'd

have the vector field right Looked like that Let's Continue

our trampling experiment dress Be told we really wanted trampling

and we might get one if we show it's for

science using our trampoline Vector field We can see that

the vectors air going in different directions so we know

option b is incorrect Now let's Think of how the

vector field would be different if the weight in the

middle was fifty pounds Well in that scenario the marvel

who had moved toward the wait at a faster speed

because the trampling would sag more And that means that

the vectors would be different because the magnitude of acceleration

would be greater So the difference in vectors allows us

to make a prediction about the source of the vector

field So one of the correct answers has to be

option d and if he is correct well then we

know that sea is incorrect but we're not done yet

We need two answers Remember now if you had the

vectors in a vector field together you confined the net

vector and that's a property of any two or more

vector So option a is the other correct answer Now

we've got that problem solved Let's get back to our

action movie screenplay were vector fields are magnitude is awesome

and our direction is wherever there's trouble way smell oscar
