Speed and energy

CONCEPTUAL
Science›Energy|Ages 9—10|ID: mt_2Um22lTBZV

Use evidence to construct an explanation relating the speed of an object to the energy of that object

Mastery Evidence

  • Explain that a moving object has energy, and the faster it moves the more energy it has
  • Provide evidence from observations (e.g. faster ball causes more damage/movement)
  • Use the term 'kinetic energy' or 'energy of motion' appropriately

Assessment Prompt

“Can [child] explain why a fast-moving ball knocks down more skittles than a slow one, using the idea that faster things have more energy?”

Prerequisites2

Show full prerequisite tree
  • Naming types of energy hard

    Relating an object's speed to its energy requires 'kinetic energy' vocabulary

  • Pushes & Pulls hard

    Must understand forces change motion before relating speed to energy

    • Drawing Force Diagrams soft

      Understanding pushes and pulls as forces is supported by the arrow representation of magnitude and direction
