Question 1

A particle is dropped from a vertical height h and falls freely for a time t.  With the aid of a sketch, explain how h varies with

            (a)        t;
            (b)        t2.

This question on projectile motion was well attempted by candidates although the performance was generally low because many candidates did not indicate the origin (0, 0).  They also could not relate how h varies with t and t2.

Observation

The expected answers are as shown below:

(a)  Diagram

Correct shape in relation to h and t                      correct shape in relation to h and t2  
h varies parabolically with t                                  h varies linearly with t2
