Newtons laws

• Newton’s first law?


  A resultant force is required to change the motion of an object
• Newtons second law? (Words)

  Acceleration of an object is proportional to the resultant force acting on it, and inversely proportional to the object‘s mass
• Newton‘s 2nd law? (Equation)

  Resultant force (N) = mass (kg) x acceleration (m/s2)
• What happens to a moving object that has no resultant force acting upon it?

  It will continue moving at the same velocity
• Newton’s 3rd law?


  When two objects interact, they exert equal opposite forces on each other
