AP Physics 1: 1.5 Object Interaction and Forces

We're not going to force you to answer this question about forces, but we suggest you gravitate towards it anyway.

believe All right what is the relationship doing Gravitational force

00:24

and electrical force Its like to answer than hear the

00:28

options Titties baby All right well let's talk for a

00:32

second about the relationship between gravitational force in electrical force

00:38

Gravitational force an electrical force share some characteristics but they're

00:42

not identical There are some very important differences between him

00:46

For example gravity is always an attractive force No we

00:50

don't mean it always looks good We mean that a

00:52

gravitational field always pulls matter inwards It never pushes matter

00:56

away But because items with identical charges repel each other

01:02

electrical forces aren't always directed in words that we can

01:06

rule out Option b also an object size isn't a

01:09

factor in determining the strength of either force You know

01:13

like a super dense black hole can have a smaller

01:15

volume than a huge star So how about electrical force

01:18

Well it's also not dependent on an object size so

01:22

option c is also incorrect and because the question asked

01:25

for two answers and we've eliminated teo while the two

01:27

remaining have to be correct right Option b is correct

01:30

because each forces stronger the closer we are to the

01:33

point of the origin that's Why astronauts in space float

01:37

there far away from the earth's gravity upton is correct

01:40

because gravitational forces and electrical forces create vector fields that

01:44

have a point of origin The sun creates the origin

01:47

Of the gravitational field that creates our solar system And

01:50

a magnet creates an electromagnetic field that attracts or repels

01:54

objects within that field That force also has a point

01:57

of origin It usually starts with a creative screenwriter Who's 00:02:00.57 --> [endTime] delusional from lack of sleep
