📚 Contact vs Non-Contact Forces

CONTACT forces — objects must touch:

  • Friction — opposes sliding motion between surfaces
  • Air resistance (drag) — friction from air molecules
  • Tension — pulling force in ropes, cables, strings
  • Normal contact force — support force perpendicular to surface
  • Upthrust — upward force from fluids (buoyancy)

NON-CONTACT forces — act at a distance:

  • Gravitational force (weight) — attraction between masses
  • Electrostatic force — between charged objects
  • Magnetic force — between magnets or magnetic materials
