What will you be able to do at the end of this chapter "Kinematics"?



1. state what is meant by speed and velocity
2. calculate average speed using distance traveled / time taken;
3. state what is meant by uniform acceleration and calculate the value of an acceleration;
4. interpret given examples of non-uniform acceleration;
5. Plot and interpret a distance-time and speed time graph;
6. deduce from the shape of distance-time graph when a body is (i) at rest    (ii) moving with uniform speed  (iii) moving with non-uniform speed;





7. deduce from the speed - time graph when a body is
 (i) at rest,
(ii) moving with uniform speed,
(iii) moving with uniform acceleration,
(iv) moving with non-uniform acceleration;
8. Calculate the area under a speed-time graph to determine the distance travelled for motion with uniform speed or uniform acceleration; and
    9. state the acceleration of free fall for a body near to the earth is constant and approximately 10 m/s2.
