Newton's laws

• Inertia = the reluctance of an object with mass to accelerate
• The greater the mass, the more inertia it has.
• newton's first law: an object remains in the same state of motion unless a resultant force acts on it
• newton's second law: force is equal to mass * acceleration

  F=ma
• newton's third law: whenever two objects interact, they exert equal and opposite forces on each other

  every action has an equal and opposite reaction
