Balanced & Unbalanced Forces
Science · Forces & Motion · procedural
Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object
What mastery looks like
- Define balanced forces (equal in size, opposite in direction — no change in motion) and unbalanced forces (cause motion to change)
- Plan a fair test investigating how different force sizes affect an object's motion
- Use results as evidence to explain when forces are balanced versus unbalanced
Check your understanding
Can Balanced & Unbalanced Forces explain why a book sitting on a table doesn't move (balanced forces) but slides when you push it (unbalanced forces)?
