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

Thank you We sneak and here's your shmoop du jour
- 00:05
brought to you by force The four fundamental forces in
- 00:08
the universe are gravitational force electromagnetic force strong nuclear force
- 00:14
and weak nuclear force There's also the force But well
- 00:18
we're told that's not a real thing despite what we

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
