Newton's First Law
Newton's Second Law
Newton's Third Law
Every action has an equal and opposite reaction
If the resultant force is zero, the object will remain at rest or constant velocity.
The acceleration of an object is proportional to the resultant force acting on the object, and inversely proportional to the mass of the object
For each situation, select which of Newton's laws applies *
