Check understanding
- Distinguish between balanced and unbalanced forces and describe the effect of each on an object's motion
- Use 'resultant force' correctly when describing the net effect of two or more forces acting on an object
- Apply 'moment', 'lever', and 'fulcrum' correctly when describing how simple machines work
“Can your child explain why a seesaw stays level when two people of different weights sit at different distances — using words like 'balanced forces' or 'moment'?”
