• Newton's second law


  A resultant force will cause an object to accelerate in the direction of the force
• Newton‘s second law equation

  Force= mass x acceleration
• Newton‘s third law


  When two objects interact, the forces they exert on each other are equal in magnitude and opposite in direction.
• What causes an object to move according to Newton‘s third law?

  • A high force
  • Object has a smaller mass
• Stopping distance

  Total distance a car travels from the moment when the driver first notices an obstruction, to when the car stops.
• Stopping distance =

  Thinking distance + Braking distance
