Thank you We sneak and here's your shmoop du jour
- 00:05
brought to you by potential fields which is where potential
- 00:08
farmers grow potential wheat Now which of the following our
- 00:12
scaler fields so like to answer our electric reelect gravitation
- 00:18
All right well let's think back to yesteryear when people

lived in caves and dinosaurs roamed the earth and we
- 00:24
were taking ap physics one Now we might have dreamed
- 00:27
the part about the caves and the dinosaurs but we
- 00:29
definitely didn't dream Ap physics one spectres are quantities that
- 00:33
have magnitude and direction scaler czar Quantities that only have
- 00:38
magnitude well Moving at one hundred miles an hour is
- 00:41
a scaler quantity moving at a hundred miles an hour
- 00:44
Heading eastbound is a vector quantity In a vector field
- 00:51
any point with that field has a quantity and a
- 00:53
direction in a scaler field Any point on lee has
- 00:56
a magnitude We know that electric fields and magnetic fields
- 01:00
are in motion They never stop moving like a puppy
- 01:03
in a dog park who answers a and c are
- 01:05
incorrect which means that being dear the correct answers in
- 01:09
potential fields there isn't any movement yet Potential energy is
- 01:13
stored there but it doesn't have a direction just like
- 01:16
potential Gravity doesn't have a direction The potential fields are
- 01:19
scaler fields then they have nothing to do with farming
- 01:22
Too bad we were looking forward to potentially making a 00:01:25.04 --> [endTime] sandwich here
