Motion - Acceleration in a straight line (UARM)
For a uniformly accelerated rectilinear motion, the trajectory (the path the moving object traces or follows) is a straight line and the acceleration is constant.
Formulas for UARM
Where:
a = Acceleration
v = final velocity (sometimes given the symbol vf)
vo = initial velocity (sometimes given the symbol u)
t = time taken
s = displacement
The unit of acceleration in the International System is m/s² . (We say ‘metres per second squared’).
If there is an increase in velocity, the acceleration is positive. If the velocity diminishes, the acceleration is negative or DECELERATION.
