Distance & speed / velocity

straight line going up distance time graph

constant speed / velocity

straight line across distance time graph

stationary

steeper line going up distance time graph

faster speed

downwards line distance time graph

negative velocity (travelling back)

What does the gradient of line in distance time graph mean

velocity

displacement

distance travelled in a given direction

upwards line in velocity time graph means

acceleration

straight flat line in velocity time graph

constant speed

downwards line in velocity time graph

deceleration

gradient of line in velocity time graph

acceleration

area underneath velocity time graph

distance travelled

define acceleration

rate of change of velocity

equation for acceleration

acceleration = change in velocity / time
