what is velocity?
the rate at which an object is moving from its initial position
how is velocity calculated?
→v = Δ→d / Δt
velocity = change in displacement / change in time
m/s = m / s
what are position-time graphs?
indicate the position of an object relative to a reference point
in graphical terms, what happens to the motion of the object as the slope becomes steeper?
it becomes speedier
what does a negative slope indicate?
a negative velocity
how can you find velocity on a graph?
finding the gradient of the slope
how do you calculate the gradient of a slope?
slope (m) = (y2 - y1) / (x2 - x1)
in graphical terms, what is displacement?
area of a velocity-time graph
how do you find the area of a graph?
A = bh
area = base x height
