A quantity that has only a size or amount is called a
scalar
vector
magnitude
direction
A quantity that has both an amount and a direction is called a
vector
scalar
magnitude
mantissa
We call how large or small a measurement is its
magnitude
mantissa
displacement
azimuth
You just ran 3 km east and 4 km south. Your Fitbit says you've traveled 7 km. The name for that measurement is your
distance traveled
displacement
speed
velocity
You just ran 3 km east and 4 km south. Your smartphone says you're 5 km southeast of your starting point. The name for that measurement is your
distance traveled
displacement
speed
velocity
The difference between speed and velocity is that
speed has a direction but velocity does not.
velocity has a direction but speed does not.
velocity is a scalar but speed is a vector.
there is none -- they're the same thing.
Mr. B walks 30 m east towards his car.
He thinks he forgot his keys, so he turns around and walks 10 m west.
He notices his keys are in his hands, so he walks the other 40 m east to his car.
This takes 30 seconds.
What distance did he travel?
10 m
40 m
60 m
80 m
Mr. B walks 30 m east towards his car.
He thinks he forgot his keys, so he turns around and walks 10 m west.
He notices his keys are in his hands, so he walks the other 40 m east to his car.
This takes 30 seconds.
What is the magnitude of his displacement?
10 m
40 m
60 m
80 m
Mr. B walks 30 m east towards his car.
He thinks he forgot his keys, so he turns around and walks 10 m west.
He notices his keys are in his hands, so he walks the other 40 m east to his car.
This takes 30 seconds.
What is the direction of his displacement?
East
West
South
Displacement doesn't have a direction, speed does.

This takes 30 seconds.
What is his average speed?
1.33 m/s
2.67 m/s
2.00 m/s
0 m/s: He's moving back and forth so it cancels out.
