Forces that change shape and equilibrium

Forces and motion • Forces and elasticity

Key concepts

What you'll likely be quizzed about

  • Forces can be categorized into contact and non-contact forces.
  • Contact forces, like friction and tension, require physical interaction between objects to exert influence.
  • Non-contact forces, such as gravitational and electromagnetic forces, act over distances without direct contact.
  • Understanding these categories helps clarify how different forces impact moving and stationary objects.
