Force & Motion Vocabulary

LANGUAGE
Science›Forces & Motion|Ages 9—11|ID: mt_F3ATPTCYm6

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

Mastery Evidence

  • 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

Assessment Prompt

“Can [child] explain why a seesaw stays level when two people of different weights sit at different distances — using words like 'balanced forces' or 'moment'?”

Prerequisites0

No prerequisites — this is a foundational topic.
