Equations of motion

We consider two types of accelerated motion:
(a) uniform acceleration where the velocity changes steadily with time, and
(b) non-uniform acceleration where the rate of change of velocity is changing with time (see acceleration file).

Equations of motion for uniform acceleration

If the acceleration of a particle is uniform the following equations apply to its motion:



where u is the initial velocity, v the final velocity, a the acceleration, t the time taken and s the displacement.

In any problem concerning these equations you would be given three quantities and asked to work out the fourth



Remember that the above set of equations can ONLY BE USED FOR UNIFORM ACCELERATED MOTION.
