average speed
the total distance travelled per total time
average velocity
the rate of change of position
acceleration
is the rate of change of velocity
deceleration
an object is experiencing a decrease in speed
speed of an object
is the distance covered over time interval
instantaneous speed
the speed of an object over a very short period of time and is the same size as the instantaneous velocity
instantaneous velocity
the rate of change in position i.e the displacement divided by a very short time period
constant acceleration
a constant increase or decrease in velocity in equal time intervals
uniform velocity
motion at constant velocity
uniform accelerated motion
the velocity of an object changes with the same amount during each interval
