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 *

A car travels at a constant speed. Drag forces are equal and opposite to the engine force
A bird flaps its wings to accelerate upwards
A book rests on a table. The weight of the book acts on the table and the reaction force of the table acts on the book
