kinematics
everything other than freefal
formulae
Δx = Vit * at^2
2aΔx = Vf^2 - Vi^2
Δx = Vave x t
a = vf-vi/t , t = vf - vi / a
Δx = area under vt graph
distance = average speed x time
graphs
vt
Δx= are under graph
a = gradient((yf - yi)/(xf - xi))
velocity(obvious)
at
acceleration(obvious)
change in velocity( area under graph)
Δxt
velocity = gradient
Δx (obvious)
if it curves, most likely have acceleration
free fall
graphs
vt
goes down then spikes up and continues to go down
at
has spikes up when the ball hits the ground, otherwise stays constant at -9.81
Δx t
looks like a ball bouncing in a direction
formula
v = g x t x 1/2
