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.
