Motion — Chapter overview · Physical Science: Matter, Forces & Energy, Grade 8
Describe movement with measurements and graphs, then use Newton’s laws to explain changes.
Chapter question
What evidence lets us describe and predict motion?
Units in this chapter
- Unit 5.1 · Speed, Velocity & Acceleration
I can calculate average speed using speed = distance ÷ time.
- Unit 5.2 · Reading Motion Graphs
I can use a position–time graph to describe rest, direction, and relative speed.
- Unit 5.3 · Newton's Three Laws of Motion
I can state Newton's three laws of motion in my own words.
- Unit 5.4 · Collisions, Deformation & Changes in Motion
I can use before–during–after records to explain temporary and remaining deformation.
- Unit 5.5 · Designing & Revising a Collision Protector
I can define a protector’s criteria and constraints and evaluate repeated test records.
