Physics - Equations of motion for constant acceleration in one dimension


Equations of motion for constant acceleration in one dimension

The equations of motion are used for constant acceleration along a
straight line - the formulae will appear on the formula sheet that is
enclosed in the exam.

Note that here _x_ (position) is used instead of _s_ (displacement). It
does not matter as long as the initial position is taken as zero. In this
case, the position is the displacement from the original position - the
terms can be used interchangeably.

All of these quantities except time are vector quantities - their
direction is indicated by their sign (positive or negative). For
convenience they are usually not written or printed using vector symbols.
They are vectors, however, and you must take the direction into account.
Therefore in using these equations you always need to define a positive
direction. It does not matter which direction you choose as long as you are
consistent in its application.
