Motion is a change in (1.).
with respect to a reference point.
Distance and displacement, speed and velocity, and acceleration are ways to
describe motion. Distance is a (2.)__quantity having magnitude but no
direction while (3.)_ is a vector quantity having both magnitude and
direction. (4.)
speed refers to the total distance travelled divided
by the total time and (5.).
is displacement divided by total time of
travel. A (6._
measures instantaneous speedivelocity.
(7.)_____motion refers to an object moving with constant speed or constant
velocity. (8.)___ is defined as the change in velocity in a time interval.
Acceleration may change in any of the following conditions: when the velocity
changes, when the (9.)
of motion changes, or when both velocity
and direction of motion changes. (10.).
is the opposite of
acceleration where the velocity of an object decreases.​
