describing motion

distance

how far object moves

scalar quantity

speed

rate of change of distance

scalar quantity

typical human walking speed

1.5m/s

typical human running speed

3m/svel

velocity

speed of object in a particular direction

vector as both magnitude and direction

displacement

vector quantity as includes distance travelled and direction of line

acceleration

rate of change of velocity

acceleration equation

change in velocity/time taken

what is acceleration measured in

m/s²

what is velocity measured in

m/s

label this distance time graph

a= increasing speed

b=constant speed

c=decreasing speed

d=stationary speed

label this velocity- time graph

a=acceleration

b=constant velocity

c=deceleration

d=stationary

how to calculate displacement from velocity time graphs

work out area underneath graph

acceleration equation using final and initial velocity

2as=v²-u²
