physics vectors
magnitude - correct answer ✔a measurement of size or amount


scalar quantity - correct answer ✔a quantity in physics such as mass,
volume, and time that can be specified by its magnitude only; it has no
direction


scalar notation - correct answer ✔the symbol for a scalar quantity, such as
time, is written in italics


coordinate system - correct answer ✔a system that establishes a zero point
location of the variable being studied and the directions in which the values of
the variable increase.


horizontally - correct answer ✔x-axis; parallel to the earth's surface


vertically - correct answer ✔y-axis; perpendicular to the earth's surface


direction - correct answer ✔up, down, left, right, away, toward, forward,
backward, north, south, east, west


positive direction - correct answer ✔(usually) up, to the right, away, forward,
north, east, counterclockwise


negative direction - correct answer ✔(usually) clockwise, down, to the left,
toward, backward, south, west

, position - correct answer ✔how far and in what direction an object is from a
reference point or point of origin


displacement - correct answer ✔how much and in what direction the position
of the object has changed


velocity - correct answer ✔the displacement of an object in one unit of time
or how fast and in what direction an object is moving


acceleration - correct answer ✔how much the velocity of the object changes
in one unit of time.


distance - correct answer ✔how far an object is separated from another
object or how long it travels along a path


speed - correct answer ✔how far an object moves in one unit of time


sign convention - correct answer ✔used for parallel vectors, it is a
description indicating which direction is treated as positive and which is
treated as negative when assigning numerical values to the magnitude of
vectors


vector direction angles and notation - correct answer ✔when vectors are not
parallel to the axes or to be precise in describing the orientation of a vector,
angles, usually measured in degrees, are used. positive= counter clockwise
and negative= clockwise. the common notation is magnitude (angle symbol)
angle


vector quantity - correct answer ✔a quantity in physics, such as position,
displacement, or force, that has both magnitude and direction.
