Success Criteria:
I am able to differentiate between scalar quantities (magnitude only) and vector quantities (magnitude and direction).
I am able to describe vectors in one dimension using correct direction conventions, such as left/right, positive/negative.
I am able to describe vectors in two dimensions in a horizontal plane using full circle bearing or quadrant bearing.
I am able to describe vectors in two dimensions in a vertical plane using angles measured as clockwise or anti-clockwise from the vertical or horizontal.
Fun Fact
Vectors are essential in computer graphics and animation. In these fields, vectors are used extensively to represent and manipulate elements such as positions, velocities, and orientations of objects in virtual 3D space. For instance, every movement of a character in a video game or animated film is typically described and animated using vector mathematics, ensuring smooth and realistic motion on screen.
Key terms
Scalars are a measurement of a physical quantity that only require a magnitude and unit. Time, distance, volume, speed and temperature are all scalar quantities.
Vectors are a measurement of a physical quantity that require a magnitude and a unit, but also a direction. Position, displacement, velocity, acceleration, force and momentum are all vector quantities.
Vector arrows are a visual representation of a vector. The length of the arrow (from tail to head) is the magnitude of the vector, the head of the arrow represents the direction of the vector.
