Chapter 5 Physics

Front 1

sketches in physics often include arrows in which each arrow represents the _____and the ____of a quantity

Back 1

magnitude and the direction

Front 2

what two things are required of a vector quantity

Back 2

direction and magnitude

Front 3

is the following sentence true or false? Velocity is a scalar quantity

Back 3

false

Front 4

what quantity is a vector quantity

Back 4

velocity, acceleration, momentum

Front 5

what best describes how two scalar quantities are multiplied

Back 5

like ordinary numbers

Front 6

write an example of a vector quantity and a scalar quantity

Back 6

vector: includes both magnitude and direction

scalar: includes only magnitude

Front 7

list each quantity that is a scalar quantity

Back 7

5 liters, 32 minutes

Front 8

can a scalar quantity be made into a vector quantity by adding a direction to its magnitude? Explain why or why not and give an example.

Back 8

not necessary it may not always make sense

Front 9

a diagram includes a 3-cm long arrow pointing to the right. The arrow is a vector scaled so that 1 cm =10m/s

Back 9

30m/s to the right

Front 10

an airplane flies in the same direction as the wind. is the following sentence true or false? the velocity of the airplane is the sum of the airplane's velocity relative to the air and the wind's velocity relative to the ground

Back 10

true

Front 11

is the following sentence true or false? a tailwind increases the velocity of an airplane

Back 11

true

Front 12

is the following sentence true or false? vectors can only be used to add velocities that are parallel to each other

Back 12

false

Front 13

the result of adding two vectors is called the

Back 13

resultant

Front 14

is the following sentence true or false? the length of the diagonal of a square is always 1.414 times the length of either side

Back 14

true
