Distance d = delta x = vt
acceleration a = 0
x=1/2 at²+v0t+x0
v=at +v0
ΔX=v0t+1/2 at²
SI UNITS
Acceleration : m/s²
speed: m/s
abscissa: m
acceleration constant
velocity: m/s
Condition of URM: straight line trajectory and constant velocity
time : seconds
speed v is constant ❌
VRM
x = vt+x0
v =d/t
Condition of UARM: straight line, constant acceleration, an=0, constant velocity
distance: m

Object with uniform accelration
rectilinear motion and varying speed but not at a constant rate then acceleration is not constant
