speed
the rate of motion
what is speed?
distance moved per unit of time
what is speed measured in?
m/s
speed formula
d divided by t
velocity
speed in a given direction
slope of a distance time graph
the speed of motion
acceleration
the rate of change of velocity
unit of acceleration
m/s2, m/s/s
how to change acceleration
changing speed or direction in relation to time
if velocity is constant
the object is not accelerating
acceleration can be
positive or negative
slope of a speed time graph
acceleration
acceleration formula
change in velocity divided by time taken
displacement
distance in a given direction
