Vectors

use vector analysis to resolve a vector into two perpendicular components

solve vector problems by resolving vectors into components, adding or subtracting the components and recombining them to determine the resultant vector. Syllabus link: Students should be able to define the term vector and determine the addition and subtraction of two vectors in one dimension
(Unit 2 Topic 1: Linear motion and force).

- Vector is a variable quantity, such as force, that has magnitude and direction

- Parallelogram method to determine resultant vector

Look through textbook for addition and subtraction of components.

Projectile motion

recall that the horizontal and vertical components of a velocity vector are
independent of each other

- Horizontal and vertical components of a velocity vector are independent of each other

apply vector analysis to determine horizontal and vertical components of projectile motion
solve problems involving projectile motion.

Syllabus link: Students should be able to recall that the acceleration due to gravity is constant near the Earth's surface and solve problems involving the equations of uniformly accelerated motion in one dimension

(Unit 2 Topic 1: Linear motion and force).

- Acceleration due to gravity (g) is constant near the Earth's surface (9.8m/s2)
