Learning path

In the order the concepts build on each other.

  1. ForceReadyA push or a pull on an object. Forces have size and direction, and they are what changes motion.
  2. PositionReadyWhere an object is, measured from a chosen origin along chosen directions. Every description of motion starts here.
  3. VelocityLockedHow fast and in which direction position changes - distance per unit time, with a direction.Opens after: Position
  4. AccelerationLockedHow quickly velocity changes - speeding up, slowing down or turning.Opens after: Velocity
  5. Newton's first lawLockedAn object keeps its velocity - stays at rest or keeps moving in a straight line - unless a net force acts on it.Opens after: Force, Velocity
  6. Newton's second lawLockedNet force equals mass times acceleration (F = ma) - the bigger the force, the bigger the change in motion; the bigger the mass, the smaller.Opens after: Newton's first law, Acceleration
