Forces Vocabulary

Science · Forces & Motion · language

Name and describe forces using precise vocabulary — force, push, pull, twist, stretch, squash, contact force, non-contact force, gravity, weight, friction, air resistance, upthrust — and distinguish between forces that require physical contact and forces that act at a distance

What mastery looks like

  • Correctly name the force acting in at least five given scenarios (e.g. 'friction slows the sledge', 'gravity pulls the apple')
  • Distinguish between contact forces (friction, upthrust) and non-contact forces (gravity, magnetism) using the correct terms
  • Use 'weight' correctly as a force — distinct from 'mass' — in descriptions

Check your understanding

If Forces Vocabulary slides down a slide and slows near the bottom, can they name the force responsible and spell it correctly?

Prerequisites

None — this is a foundational concept.
