Learning Objectives
Indicator: B7.3.2.3.3 - Distinguish between scalar and vector quantities
By the end of the lesson, learners can:
- Define scalar quantity and vector quantity in their own words, giving at least two examples of each.
- Classify given physical quantities (such as weight, force, velocity, time, speed, distance, mass, volume, energy, work, momentum) correctly as either scalar or vector quantities.
- Identify the magnitude and direction of a given vector, including recognising a zero vector as a point with no magnitude and direction.
- Draw a vector given its length and bearing, such as TS = (6 km, 245°), using a protractor and ruler.
- Explain a vector as a movement (distance) along a given bearing, using examples from everyday journeys.

Exemplars (from the NaCCA curriculum)
E.g.1 Read on scalar quantity and vector quantity on the internet. E.g.2 Group these examples under scalar quantity and vector quantity, weight, force, velocity time, speed, distance, mass, volume, energy, work momentum etc… E.g.3 Identify a vector as a movement (distance) along a given bearing E.g.4 Draw a vector given its length and bearing E.g. TS ⃗ =. (6km,245˚). E.g.5 Identify the distance along a vector as its magnitude and the 3 - digit clockwise angle from the north as its bearing E.g.6 Identify a zero vector as a point with no magnitude and direction.
