Motion Along A Straight Line
The following particle is moving in a straight line.
Define the following variables:
is the position of the particle as a function of time
is the change in position of the particle
is the velocity of the particle
is the acceleration of the particle
If we assume constant acceleration, we have the following formulas. Note that the subscripts 1 and 2 denote "initial" and "final".
These formulas also apply to bodies which are moving in a straight line, with no rotation. This means that every particle in the body is following the same path.
