Newton's Laws

• What is Newton's First Law?

   An object remains in the same state of motion unless a resultant force acts on it. If the resultant force on an object is zero, this means:

  • a stationary object stays stationary
  • a moving object continues to move at the same velocity (at the same speed and in the same direction)
• What is Newton's Second Law?

  Force equals mass times acceleration.
• What is Newton's Third Law?

  When two objects interact they exert equal and opposite forces on eachother
• What is inertia?

  Tendency for motion to remain unchanged
