Define distance.
the relationship between to objects
the motion of an object between two points in space
the position of a point in space
the separation between any two point in space
What does position mean in physics?
the distance of an object
the same origin point in space
a unique location in space
the distance between two objects in space
How is distance different from position?
position is always positive, but distance can be negative
position implies an origin
distance is relative to speed
position is below the origin and distance is above it
What is a displacement?
a change in position
a change in the origin
a coordinate system
two different origin points
What is a vector?
a type of variable with the same origin point
a type of variable that includes direction as well as size
a variable with only positive values and shows direction
a displacement with no direction and no magnitude
A scalar does not depend on _____.
position
distance
magnitude
direction
Which of the following is a vector?
distance
mass
displacement
temperature
What is the difference between distance and displacement?
both show movement, so they are the same
one is a vector and the other is a scalar
distance shows direction, displacement does not
With a vector, what kind of information is carried by the positive and negative signs?
the direction
the size
the math function
the coordinates
What is the "magnitude" of a vector?
the units of the vector show magnitude
the sign of the vector shows magnitude
the length of the vector shows magnitude
the direction of the vector shows magnitude
direction

what is kinematic
branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved
a force
a solution
the unit we measure time is in ___.
m/s
m
