Hook
Distance or displacement?
- 5 km around a track vs 0 km displacement.
- Direction matters for vectors.
Units / Unit B / Scalars, Vectors, and One-Dimensional Motion
Scalars, Vectors, and One-Dimensional Motion
Scalars vs vectors; displacement, velocity, acceleration; constant speed (B-GO2-SO4–SO7).
Outcome checklist
Alberta Program of Studies — tick each row when you can explain it without the slide.
- B-GO2-SO4
By the end of this lesson you should be able to: Define, compare and contrast scalar and vector quantities
Self-check: Without looking at your notes, give one example or explanation that shows you meet B-GO2-SO4.
- B-GO2-SO5
By the end of this lesson you should be able to: Describe displacement and velocity quantitatively
Self-check: Without looking at your notes, give one example or explanation that shows you meet B-GO2-SO5.
- B-GO2-SO6
By the end of this lesson you should be able to: Define acceleration, quantitatively, as a change in velocity during a time interval: a = Δv/Δt
Self-check: Without looking at your notes, give one example or explanation that shows you meet B-GO2-SO6.
- B-GO2-SO7
By the end of this lesson you should be able to: Explain that, in the absence of resistive forces, motion at constant speed requires no energy input
Self-check: Without looking at your notes, give one example or explanation that shows you meet B-GO2-SO7.
- B-GO2
Big idea: Explain and apply concepts used in theoretical and practical measures of energy in mechanical systems
Self-check: How does today's lesson connect to B-GO2?
Where this shows up later
- Unit B — Energy technologies: Vectors describe motion in energy systems.
