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

- 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:
2.4 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

Calculate time of flight, maximum height, range and
maximum range, instantaneous
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
