UNIT 1
MODULE 1: MECHANICS (cont’d)

SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

SI Units (cont’d)

Students should be able to:

2.4. use base units to check the
homogeneity of physical
equations.

3. Motions

Students should be able to:

3.1. explain displacement,
speed, velocity, and
acceleration;

3.2. use graphs to represent Perform experiments using
displacement, speed, an object rolled down an
velocity, and acceleration inclined plane, for example,
in a single dimension; a marble rolled down an
inclined PVC gutting.

3.3. use the gradient of and
area under motion graphs
to solve problems;

3.4. derive equations A non-calculus approach
representing uniformly may be used:
accelerated motion in a
single dimension; v = u + at

v = u + 2as

(u + v)t
s =

3.5. use the equations of
motion to solve problems,
on uniformly accelerated
motion;
