Physics
Kinematics
Units
Distance - Meters (m)
Total length of journey travelled
D = S x T
Speed - (m/s or ms-^2)
Distance/time
Acceleration - m/s^2
Rate of Speed of Change
A = (end velocity -initial velocity)/time
Vector or Scalar
Scalar Quantities only measure magnitude. These can be speed of distance.
Vector Quantities measure magnitude and direction. These can be displacement, velocity or acceleration.
SUVAT Equations
s = displacement
• u = initial velocity
• v = final velocity
• a = acceleration
• t = time
Different SUVAT Equations
a = (v-u)/t
s = ut + 1/2at^2
s = vt + 1/2at^2
v^2 = u^2 + 2as
s = (u + v)/2) x 2
