average speed the total distance something has traveled divided by the total time it has traveled
constant speed Speed that does not change
instantaneous speed the speed at a certain given moment
Velocity the speed of an object in a particular direction
Vector quantities that are fully described by both a magnitude and a direction
Acceleration the rate at which velocity changes with time
deceleration negative acceleration
meters per second (m/s) Speed is most commonly measured in
seconds Time is most commonly measured in
meters Distance is most commonly measured in
distance/time formula for speed
displacement/time formula for velocity
scalar quantity What type of quantity is speed?
