One equation that describes motion of an object under certain conditions is
X =
at12
where x is the position of the object with units of
meters, a is the acceleration with units of meters per
second squared, and t is time with units of seconds.
Show that the dimensions in the equation are
consistent.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
