V = d/t
V-> = Dr / t
a = v / t = v2 - v1 / t
slope = rise / run
V2 = v1 + a * t
v1 = v2 - a * t
Refereance Point - All distances are realitive to a reference poiint which is usually the orgin of starting point.
Position - Seperation / irection from a reference point.
Vector Quanity - A quanity that includes a direction and a size
eg 200m(s)
Reresneed by symbols witha small arrorw of the quanity.
Scalar - Has no direction .
M - 3.6
Gravity - 9.81
Average Vecoloity
vav = dr/t
Uniform - Average movmenet - Same Speed
Distance Time graphs
y axis refers to the distance away from the organ at a given time
X - Axis - X axis refers to the time ovr the observated interval
Slope - Rise / Run - Distance Time = Speed
Spped - Time
yaxis " " speed"
x - axis - Still time =
Slope = Rise / Run = Speed / Time = Accerlation
Sclar = Distance
Vectory = Direction

a = v2 - v1 / t
Now
v2 = V1 + at
v1 = v2 * at
t = v2 - v1 / a
Gravity 9.8 m/s2
1m/s = 3.6km/h
Velocity Foruma
V-> = d/t
Now: d = v*t
t = d/v
