Force & Motion Vocabulary
Use technical vocabulary for force and motion — balanced forces, unbalanced forces, resultant force, acceleration, deceleration, speed, moment, lever, fulcrum, mechanical advantage — and apply these when explaining and predicting how forces affect the motion and position of objects
Lesson
Set out your lesson
“Force & Motion Vocabulary means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A small toy car or ball
- A ramp or book stack and a ruler
Extra for the adult
Worked example. A stronger push sends the car farther down the table than a gentle push.
Optional challenge. For Force & Motion Vocabulary, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Force & Motion Vocabulary, not mastery.

Force & Motion Vocabulary means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A small toy car or ball; A ramp or book stack and a ruler. 1. Say the goal of Force & Motion Vocabulary in plain words once. 2. Adult gives one gentle push and one stronger push, then compares how far the object travels. 3. Child tries three push or pull trials and records which force made a bigger change. 4. Fresh check: one fresh push/pull comparison. Record and stop. Done: three recorded trials with a clear force comparison. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

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'?”
