Equations of motion ESAHG
In this section we will look at the third way to describe motion. We have looked at describ-
ing motion in terms of words and graphs. In this section we examine equations that can be
used to describe motion.
This section is about solving problems relating to uniformly accelerated motion. In other
words, motion at constant acceleration.
The following are the variables that will be used in this section:
~vi = initial velocity ( m·s−^1 ) att= 0 s
~vf = final velocity (m·s−^1 ) at timet
∆~x = displacement (m)
t = time (s)
∆t = time interval (s)
~a = acceleration (m·s−^2 )
An alternate convention for some of the variables exists that you will likely encounter so
