Project task (20% assessment)You are a scientist
who is tasked by
A*Star to explain a
complex motion and
the cause of the
motion. You are to
record a video of a
moving object and to
analyse the kinematics
and dynamics involved
in the motion with the
aid of Tracker
software. Your report
will help the scientific
community better
understand the
complex motion.
