Three laws of inertia

• An example of Newton's First Law is a car parked on a hill. If it isn't pushed, it will remain stationary until a force acts on it.
• Second Law of Inertia

  The acceleration of an object is directly proportional to the force acting upon it and inversely proportional to its mass.
• Third Law of Inertia

  For every action, there is an equal and opposite reaction.
