Vectors and Two Dimensional Motion Flashcards
A vector quantity has both magnitude (size) and
direction
Vector
A ____ is completely specified by only a
magnitude (size)
Scalar
The ____ is defined as the vector
that gives zero when added to the original vector
Negative Vector
If the scalar is ____, the direction of the result
is the same as of the original vector
Positive
If the scalar is ____, the direction of the
result is opposite that of the original vector
Negative
is the ratio of the
displacement to the time interval for the
displacement
Average Velocity
as the rate at
which the velocity changes
Average Acceleration
➢ An object may move in both the x and y
directions simultaneously
o It moves in two dimensions
➢ The form of two-dimensional motion we will
deal with is an important special case called
_____
Projectile Motion
about relating the
measurements of two different observers
Relative Velocity
