Kinematics
Formulae for constant acceleration
v = u + a t
v^2 = u^2 + 2a(Sf - Si)
Sf = Si + u t + 1/2 a t^2
v = final velocity (m/s)
u = initial velocity (m/s)
a = acceleration (m/s)^2)
Sf = final position (m)
Si = initial position
t = time taken (s)
Definitions
Displacement
vector quantity
SI unit is (m)
denoted by s
it is the distance measured from a reference point to the final position of a point
Velocity
vector quantity
SI unit is (m/s)
denoted by v
it is the rate of change of displacement
Acceleration
SI unit is (m/s^2)
denoted by a
is the rate of change of velocity with respect to time
On a velocity-time graph
area under the graph represents displacement
gradient represents acceleration
