Thank you We sneak Then here's your shmoop du jour
- 00:06
brought to you by ignoring forces We tried ignoring gravity
- 00:10
once And well it didn't work out so well in
- 00:13
which situation can electromagnetic strong and weak forces be ignored
- 00:19
And here are potential answers All right Like them all
Full Transcript
- 00:25
right Well the four fundamental forces are the strong force
- 00:29
the weak force thie electromagnetic force and gravitational force right
- 00:36
We've learned that we've memorized it We chanted in our
- 00:39
sleep And the force works on different scales The strong
- 00:46
force binds nuclear ons to form atoms and the weak
- 00:50
force is responsible for radioactive decay Well these forces act
- 00:55
at a subatomic level If we're dealing with particles larger
- 00:58
than the size of atoms or distance is larger than
- 01:01
one fifteenth of a meter Well then these forces won't
- 01:04
apply when a nucleus undergoes beta decay is an answer
- 01:08
c that's the weak force in action so that's not
- 01:11
correct answer And when to nuclear ens moved toward each
- 01:14
other at a low speed while that's a result of
- 01:16
electromagnetic force at a subatomic level There's just not enough
- 01:20
mass for gravity to exert much of an influence The
- 01:24
answer is out too well His light travel through space
- 01:27
It can be affected by gravity But light is an
- 01:30
example of an electromagnetic wave so we can't exactly ignore
- 01:34
the electromagnetic force when it comes to light Answer d
- 01:37
is wrong too That means the correct answer is b
- 01:40
when we're dealing with objects of this size the strong
- 01:43
and weak forces definitely don't fly and electromagnetism wouldn't apply
- 01:49
either since both jupiter and its moons are neutrally charged
- 01:53
plus it would take a huge amount of electromagnetism The
- 01:55
influence something is largest moon much less huber The things
- 01:59
that beast moon's orbit planets because they're influenced by the
- 02:02
planet's gravity all the other forces can be a pretty
- 02:05
much ignored At least they could be ignored for this
- 02:08
question saying But remember just because you ignore a fundamental 00:02:11.25 --> [endTime] force doesn't mean that it ignores you
