1.2 Scalars and Vectors (1 hour)
LEARNING OUTCOMES
a) Define scalar and vector quantities, unit vectors in
Cartesian coordinate.
b) Perform vector addition and subtraction operations
graphically.
c) Resolve vector into two perpendicular components
(2-D) a

Recall
Addition of vectors in the same directions
Addition of vectors in the opposite directions
The direction of
resultant vector S is
in the direction of
the bigger vector
For two or more coplanar vectors point in different
directions can be added by us

Learning Outcome:
2.4 Projectile motion (2 hours)
At the end of this chapter, students should be able to:
Describe and use equations for projectile,
a x 0
a y g
1
Calculate time of flight, maximum height, range and
maximum range, instantaneous

- Velocity is vector quantity, a change in
velocity may thus involve either or both
magnitude & direction.
- An acceleration may due to the change in
speed

Learning Outcome:
2.1 Linear Motion (1 hour)
At the end of this chapter, students should be able to:
Define and distinguish between
distance and displacement
speed and velocity
average velocity, instantaneous velocity and uniform velocity
instantaneous ac

Learning Outcome:
