Newton's First Law

Cards (10)

  • Newton's First Law
    Motion will not change unless an unbalanced or net force acts on it.
  • Unbalanced Force
    Net force.
    Can make an object at rest move.
  • Balanced Forces
    Equal forces cancelling out.
    This makes an object move at a constant speed or stay stationary.
  • The greater the mass, the greater the inertia.
  • The less mass, the less inertia.
  • When a car collides into an obstacle, it stops instantly. Due to the passengers' inertia they will continue to move forward until they're stopped by the seatbelt, steering wheel or windshield.
  • Newton's First Law in action
  • Newton's First Law is also the law of inertia.
  • Inertia
    The tendency to resist change.
  • Would the tablecloth trick work better with paper dishes?
    No, it would be more difficult. The paper dishes have less mass and therefore, less inertia.
