2 displacement and velocity

define displacement

vector, distance in a vertical direction

define velocity

the rate of change of displacement

what’s the equation for velocity?

velocity = displacement/time

what does the gradient represent in an displacement time graph?

the velocity of an object

what does a positive gradient show in a displacement time graph?

a constant velocity

what does a straight line with no gradient on a displacement time graph show?

the object is stationary

what does a negative gradient on a displacement time graph show?

the displacement is getting smaller and it’s returning to a constant velocity

how can the velocity of an object be determined using the displacement time graph?

calculating the the gradient by drawing a tangent to the graph

define instantaneous velocity

the velocity at a particular point in time

how can the instantaneous velocity be found on a graph?

draw a tangent to on the point you want to find and then do change in y/change in x

if something moves back to its original position, what will its displacement be?
